Answer:

8.82 x 10^{5}

Step-by-step explanation:

\frac{speed of light}{speed of sound} = \frac{3*10^{8} }{3.4*10^{2} } = 8.82*10^{5}

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:

  • x = 28
  • 132°

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>

  • 3*28 + 48 = 132°
