Find the measure of x, then find the measure of each angle
1 answer:
First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:
180° = 90° + (x/2) + (7x - 90°)
180° = x/2 + 7x
180° = x *(1/2 + 7)
180° = x*(15/2)
2/15 * 180° = x
24 = x
Angle A:
A= x/2
A = 24/2
A = 12°
Angle B:
B = 7x
B = 7*24
B = 168°
The two bottom angles are both worth 90°.

Step-by-step explanation:
Simplest form=10/30=1/3
=1cm:3cm
Simplest form=2cm:1m
1m=100cm
2:100
2/100=1/50
1cm:50cm
We complete everything as follows

Step-by-step explanation:
3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9
6x + 24 = 6 - 6x
12x = -18
x = -1.5
