Answer:
B
Step-by-step explanation:
2x-3=7
Add 3 to both sides:
2x=10
Divide both sides by 2:
x=5
Hope this helps!
A sector is the area bounded by two radii and the included arc.
To calculate for the area of the sector, you’ll use the formula A=n/360(pi)(radius)

.
The n in the formula refers to the measure of the central angle in degrees.
The given data in the problem is in radians, convert it by multiplying 1.25 by

.
Now input the converted value to the formula of finding the area of the sector.<span>

Answer:
126 square feet
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh . . . . . where b is the base length and h is the height
Here, you have a triangular face that has a base of 6 ft and a height of 14 ft. Its area is ...
A = (1/2)(6 ft)(14 ft) = 42 ft^2
The lateral area of the pyramid consists of 3 such triangles, so the lateral area is ...
LA = 3·(42 ft^2) = 126 ft^2
The answer is 19.6 cm^2
you should find the height of the triangle by heron formula: it will be 9.8
so the area is

good luck
