Answer:

(2A)/h -a =b

Step-by-step explanation:

A= [h(a+b)]/2       I rewrote the formula, because h and a+b are in the numerator.

2A=h(a+b)  Multiply both sides of equation by 2

(2A)/h= a+b Divide both side by h

(2A)/h -a= b Subtract a from both sides

in the diagram,transversal t intersects parallel lines m and n. Classify the given angle pair. then determine each measures.​
professor190 [17]

Answer:

Step-by-step explanation:

Corresponding angles: ∠2=∠ 6  ;  ∠1 = ∠5 ;    ∠4 = ∠8;  ∠3 =∠7

Vertically opposite angles: ∠1 = ∠3;  ∠2 = 4;  ∠5 = ∠7 ;  ∠6 = ∠8

Interior angles : ∠4, ∠3 , ∠6, ∠7

alternate interior angles are equal: ∠3 = ∠5 ;  ∠4 = ∠6

Maurinko [17]

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²
