I have no clue what the answer would be, I’ve worked on it for 25 minutes, I will get back to you if I figure it out :,)
Answer:
see explanation
Step-by-step explanation:
the perimeter is the sum of the 3 sides of the triangle
add the parts of the ratio 21 + 8 + 14 = 43
divide the perimeter by 43 to find the value of one part of the ratio
= 5 ft ← 1 part of the ratio, hence
21 parts = 21 × 5 = 105 ft
8 parts = 8 × 5 = 40 ft
14 parts = 14 × 5 = 70 ft
the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
8.213, 8.214 just add 1 hundred to the end
The statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle
<h3>What is a Right Angle?</h3>
A right angle is an angle that measures 90 degrees.
Given the diagram, where:
m<AGC = 38°,
m<CGD = 71°,
m<FGC = 147°
We have the following measures:
1/2(m<AGC) = m<AGB
1/2(38) = 19°
m<CGD + m<AGC = m<BGD
Substitute
71 + 19 = m<BGD
90 = m<BGD
m<BGD = 90° [this is a right angle].
Therefore, the statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle
