Angle A and angle B are complementary angles. If m∡a = 4x and m∡b = 3x +13, what is the measure of the smaller angle?
bagirrra123 [75]

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:

Mikaya and Olivia are correct to be suspicious

Step-by-step explanation:

Sum of the angles of a triangle is always 180

But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180

So, Zuri is wrong
