Answer:
A
Step-by-step explanation:
3x and x + 30 are vertically opposite angles and are congruent , then
3x = x + 30 ( subtract x from both sides )
2x = 30 ( divide both sides by 2 )
x = 15
Then
∠ A = 3x = 3(15) = 45°
See <A and x+30 are opposite angles .
We know that opposite angles are equal
so
3x=x+302x=30x=15Now
<A=3x=45°Option A is correct

Answers
Answer: 0
Step-by-step explanation:
We can start by factoring out an a from all 3 terms:
= a (1 + 2 - 3)
We can evaluate 1 + 2 - 3 as 0:
= a(0)
Anything multiplied by 0 is 0, therefore 0a = 0.

a) 9
b) 11
c) 12
d) 13
Please explain how you got the answer
Answers
Answer:
d
Step-by-step explanation:
given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
21 - 9 < x < 21 + 9 , so
12 < x < 30
the only value that satisfies the inequality is 13

Answers

Step-by-step explanation:
The perimeter of a triangle is 31 cm. Sides #1 and #2 have equal length, while Side #3 is one centimeter shorter than twice the length of Side #1. Let's determine how long each side is: a. Let x represent the length of Side #1. What essential part of this "let" statement is missing? What is the length of Side #2? Side #3? b. Write a mathematical sentence that states that the perimeter is 31 cm. c. Solve the equation you found in part (b) and determine the length of each side. Be sure to label your answers with the appropriate units.
Answer:
8 cm, 8 cm, 15 cm
Step-by-step explanation:
The given relationships between the sides can be used to write an equation. Let s represent the length of side 1. Then side 2 has a length that is also s. Side 3 has length (2s-1). The perimeter is the sum of the side lengths:
s + s + (2s -1) = 31
4s = 32 . . . . . . . . . . collect terms, add 1
s = 8 . . . . . . . . . . divide by 4

C. package of sugar cookie dough: $10, package of gingerbread cookie dough: $8
D. package of sugar cookie dough: $5, package of gingerbread cookie dough: $20
Answers
Explanation: Form 2 simultaneous equations
9s+9g=162 for Kristin (equation 1)
13s+8g=169 for Julio (equation 2)
If you get the coefficients for g to the same number you get
72s+72g=1296 (equation 1)
117s+72g=1521(equation 2)
You can then take equation 2 away from equation 1 leaving you with
45s=225
s=5
Then sub s=5 into the original equation
9s+9g=162
9x5+9g=162
45+9g=162
9g=117
g=13
Therefore s=$5 and g=$13

Answer:
x = 5, x = 7
Step-by-step explanation:
tangents from an external point to a circle are congruent , then
x² = 12x - 35 ( subtract 12x - 35 from both sides )
x² - 12x + 35 = 0
(x - 5)(x - 7) = 0
equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5

Answer:
The distance between -1,12 and -1,-3 is 15
Step-by-step explanation:
Simplify-
Multiply −1 by −1.
√(−1+1)^2 + ((−3) −12)^2
Add −1 and 1.
√0^2 + ((−3) −12)^2
Raising 0 to any positive power yields 0.
√0 + ((−3) −12)^2
Subtract 12 from −3.
√0 + (−15)^2
Raise −15 to the power of 2.
√0 + 225
Add 0 and 225.
√225
Rewrite 225 as 15^2.
√15^2
Pull terms out from under the radical, assuming positive real numbers.
