Find the value of X. | Please help me!!
Answer:
x=90 degrees
Step-by-step explanation:
A pentagon's angles should add up to 540 degrees. There are 6 angles shown, two are given ( the bottom two are right angles which are 90 degree angles). So 560 divided by 6 [angles] is 90[degrees]. So, each angle is 90 degrees.

The sub for b is 14
Answer:
44
Step-by-step explanation:
I'm assuming you're meant to multiply so I did 3(14)+2 and it gave me 44 :)
Answer:
so it should be 44
Step-by-step explanation:
So the sub for b is 14 so substitute the b to 14
Then 3(14) they are multiplying so multiply them should equal 42
Then add the 2 the answer should be 44

Calculate the slope of a line through the points
(2, 1.5) and (-5, 36.5).
Answer:
35/-7
Step-by-step explanation:
you want to do the second y- the first y over the second X- the first x to GRT the slope
Answer:
35/-7
Step-by-step explanation:
To calculate slope, you use the slope formula: y2 - y1
x2 - x1
So 36.5 - 1.5
-5 - 2
And that equals 35/-7

1. Write the equation of the line with y-intercept 3
and a slope of -2/3and graph it.
Answer:
y=[tex]\frac{-2}{3}[/tex]+3
Step-by-step explanation:
The equation is y=mx+b
m is your slope
b is your y-intercept
The graph should cross the y-intercept on the y-axis 3 and be a negative slope (left to right diagonal) Place a point on y=3 go down 2 and then right 3

whats the value of x
A 95
B 105
C 75
D 85
Answer:
D. 85
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.
180 - 40 - 55 = 85
Answer:
85 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180, so we can set up an equation
x+40+55=180
Now all we need to do is to subtract 40 and 55 from both sides
x+55=180-40=140
x=140-55=85
x=85
