Answer:
Step-by-step explanation:
Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.
4x+3x+13=90
-13 -13
7x=77
/7 /7
X=11
Now plug in the value of x.
A=4(11) B=3(11)+13
A=44. B=33+13
B=46
Angle a is the smaller angle and measures at 44°
Answer:
Step-by-step explanation:
<u>The two marked angles must have same value as corresponding angles:</u>
- 3x + 48 = 6x - 36
- 6x - 3x = 48 + 36
- 3x = 84
- x = 28
<u>The angle measure:</u>
D 8x-3 because must add them all together
0.84 repeating. Hope this helped.
