I know a=pi*r^2 anyways, the triangle is:4*8/2=16 The semicircle is: 4pi because 4 is diameter, /2 then square u still get 4. 4*3.14 = 12.56 12.56 + 16 = 28.56.
The value of x is x = 2
Explanation:
The equation is
To solve the equation using inverse operations, let us do the following steps:
Adding 4 on both sides of the equation, we get,
Simplifying, we get,
Dividing both sides by 7, we have,
Simplifying the terms, we have,
Thus, the value of x is 2.
Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
Answer: 10
Step-by-step explanation:
use a^2 + b^2 = c^2
where a = |y2 - y1| = 11 - 3 = 8
where b = |x2 - x1| = |-2 - 4| = |-6| = 6
8^2 + 6^2 = c^2
100^2 = c^2
c = 10
