Answer:
19 1/6
Step-by-step explanation:
Because 15 divided by 180 is 0.08333333333.
times that by 230 = 19.166666666 or 19 1/6
10 and try using photomath it helps.
(4x+7)/5 = 58
Cross Multiply:
4x+7 = 5*58
4x + 7 = 290
Subtract 7 from both sides:
4x = 283
Divide by 4 on each side:
x = 70.75
D) 70.75! :)
Answer:
x = 94°
Step-by-step explanation:
The total always equals 360° (except triangles).
So
73 + 112 + 81 + x = 360
266 + x = 360
x = 360 - 266
x = 94°
