I do not know that answer that is hard
Answer:
x ≈ 6.8
Step-by-step explanation:
since all angles in a triangle add up to 180º:
8x-4+17x-23+3x+17=180
28x-10=180
28x=190
x ≈ 6.8
Answer:
30 cm²
Step-by-step explanation:
we need to find h
V=πr²h
h=V/πr²
h=210/14²π
h=0.341
then we found curved surface area
A=2πrh
A=2×π×14×0.341
curved surface are= 30 cm²
The sum of the angles of a triangle is equal to 180°.
x+65+79 = 180
x = 180 - 65 - 79
x = 36°
