Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches

Electric current can be measured on a numeric scale e.g. eclectic current is 50 volts
Direct variation/proportional means that one variable is always a multiple of the other variable.
It looks something like
, where n is any number.
