Elden [556K]2 years ago

Answer:

It's a isosceles triangle, i am not saying its clearly implied in the diagram with the red lines.... Which state that both the sides have same length

Hence if on ne side makes 55 with the base therefore the side with same length will make 55 with the base too

Hence its

55+55+x=180

X= 180-55-55

X= 70 degree

Therefore x is 70 degree

What are the measures of the angles in triangle ABC?
VMariaS [17]

Complete question :

A right triangle has side lengths AC = 7 inches, BC = 24 inches, and AB = 25 inches.

What are the measures of the angles in triangle ABC?

a) m∠A ≈ 46.2°, m∠B ≈ 43.8°, m∠C ≈ 90°

b) m∠A ≈ 73.0°, m∠B ≈ 17.0°, m∠C ≈ 90°

c) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°

d) m∠A ≈ 74.4°, m∠B ≈ 15.6°, m∠C ≈ 90°

Answer:

c) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°

Step-by-step explanation:

Given:

Length AC = 7 inches

Length BC = 24 inches

Length AB = 25 inches

Since it is a right angle triangle,

m∠C = 90°

To find the measures of the angle in ∠A and ∠B, we have :

For ∠A:

SinA = \frac{BC}{AB}

SinA = \frac{24}{25}

SinA = 0.96

A = Sin^-^1 = 0.96

∠A = 73.7°

For ∠B:

SinB = \frac{AC}{AB}

SinB = \frac{7}{25}

SinB = 0.28

B = Sin^-^1 = 0.96

∠B = 16.26 ≈ 16.3°

Therefore,

m∠A = 73.7°

m∠B = 16.3°

m∠C = 90°

On his vacation, Chad spent 1/8 of the day swimming, 1/6 of the day shopping, and 1/4 of the day water skiing. How much of the d
Anastaziya [24]

Answer:

11/24

Step-by-step explanation:

First find the common denominators of each fraction:

The common denominator of each fraction is 24

  • 1/8 multiplied by 3 is 3/24
  • 1/6 multiplied by 4 is 4/24
  • 1/4 multiplied my 6 is 6/24

add these fractions up

3/24 + 4/24 + 6/24 = 13/24

subtract 24/24 - 13/24 = 11/24

Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina's rate in mil
LuckyWell [14K]

convert feet to miles

63360/5280 = 12 miles

convert seconds to hours, there are 3600 seconds per hour

3400/3600 = 0.94 hours

since Nina rode 12 miles in 0.94 hours she is faster ( rode further in less time)
