Answer:
Just do (2x-3)+(x-5)+(x)=180°
Step-by-step explanation:
It is sum of angles of triangle
Answer:
30m
Step-by-step explanation:
A=πr²
225π=πr²
225=r²
r=√225
r=15
d=2r
d=2×15
=30m
Answer:
The answer is 40 sq. units
That is: 1/2×b×h (formula for area of triangle)
1/2×10×8
= 40
Answer:
39062.5
Step-by-step explanation:
-2+-10+-50+-250
-10/2=-250/-50 = 5
sum of the geometric sequence
Sₙ = arⁿ⁻¹ /r-1 a=-2, r = 5
S₈ = -2(5)⁸⁻¹/(5-1) = 2(5⁷)/4 = 2(78125)/4= 78125/2= 39062.5
S₈=39062.5
-11
Hope this answer helped :)
