Answer:
honestly this is very confusing could you send a graph?
Step-by-step explanation:
Answer:
3.Area=πr²
d=14ft
r=7 ft
22/7*7*7
area=154ft²
5.area =1/2 bh
h=13cm
area=32.5cm²
32.5=1/2*13*b
32.5=13/2b
=5.0 or 5
base=5cm
Step-by-step explanation:
Answer:
<h2><u><em>
55°</em></u></h2>
Step-by-step explanation:
the sum of the interior angles of a triangles is 180°
so
180 = 75 + 50 + x
x = 180 - 75 - 50
x = 55°
-----------------------
check
55 + 75 + 50 = 180°
the answer is good
Answer:
1.44 units²
Step-by-step explanation:
The angle for the big triangle is 60°, so the smaller triangle is 30°
so to find the base of the small triangle you can do tan 30 = X/2
so x is 2, which means that the base of the big triangle is 4.
The area of the big triangle is 1/2bh = 1/2(4)(2
) = 4
= 6.93
Find hypotenuse (radius) using Pythagorean Theorem r = 4
The area of the piece of pie is
= 8.37
8.37 - 6.93 = 1.44
It means they are both equal
