The area of a triangle is given by the expression 4x + 20, in square feet. It’s height is 8 feet as shown. it’s base is an unknown in terms of the variable x. a) write the area of the triangle as the product. b) For what vale of x will the height and the base be the same length? Justify. c) check your answer to by using A=1/2b*h and by substituting it into the expression A= 4x+ 20.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

i think the answer is true

step-by-step explanation:

d.) yes, because the volume of the cone is greater than the volume of the sphere
