Start by adding together the shortest two sides, 7 and 8.7 inches. Result: 15.7 inches. Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.
Step-by-step explanation:
The answer is D: 5.17 , x 10-1 , 5/8 , 50% , 0.43
Step-by-step explanation:
QR = ST
⅔x = 0.4
times 3
2x = 1.2
x = 1.2 /2
x = 0.6
A 61° angle because a triangle’s angles need to add up to 180° and 90+29=119 then 180-119= 61.
