to find the constant of proportionality here let's look at the equation of a line for a straight graph that passes through the origin. y is your vertical y-value for any given point on the line, x is your horizontal x-value for any given point on the line, and m is the slope.
A = 1/2 hb
20 = 1/2 x 4 x b
20 = 2 b
b = 20 /2
b = 10
answer is <span>10 m</span>
To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
Answer:
i think one is -2^2
Step-by-step explanation:
Answer:
154 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon is 540.
Hence to get the 2 angles,
52+90+90+2n = 540
232 + 2n = 540
2n = 308
n = 154
