Answer: x= 19
Step-by-step explanation:
(8x-7)+(x+16)=180
22 - 4x = -5, add 5 to both sides, add 4x to both sides
22 + 5 = 4x
27 = 4x
x =6.75
7 would be the smallest number; 7 * 28 = 196 and the square root of 196 is 14.
Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 3<em>4200</em>
