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
Answer:
13/6
Step-by-step explanation:
2 5/6=17/6
w+2/3=17/6
w=17/6-2/3
w=17/6-4/6
w=13/6
Twice(2*) the measure of an angle(x)'s compliment(180°-x) less than 6(-6) is equal to 124°.
Thus your answer is 115°
Answer: 4
Step-by-step explanation: 3 + 4 = 7 and 4 x 7 is 28. If you're 16 and 12 you also get 28
