<span>D-21.4=87.9 \ solve for D
add 21.4 to both sides
</span><span>D - 21.4 +21.4 =87.9 + 21.4
simplify
D = 109.3</span>
Answer:
so the question is very interesting and the answer is 12 × 15 so the answer is 180 rolls of ribbons
Answer:
x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.
Answer:
3
Step-by-step explanation:
3/4 (5x -3)+8=17
3/4 (5x -3) = 17 - 8 = 9
(5x -3) = 9 * (4/3)= 36/3 = 12
5x = 12 + 3 = 15
x = 3
