Answer:
a = 33
Step-by-step explanation:
IN a parallelogram consecutive angles are supplementary, thus
5a - 52 + 5a - 98 = 180, that is
10a - 150 = 180 ( add 150 to both sides )
10a = 330 ( divide both sides by 10 )
a = 33
Answer:
a3 + b3 = a3 + b3
Step-by-step explanation:
I'm not sure what you are asking for but this equation is true if that's the problem.
Multiply all the variables and then combine like terms.
On the left side we end out as a3 + b3 which is equal to the right side. Hope this helps!
I don't know I think c=23 hope you get it right good luck lol
Answer:
Step-by-step explanation:
Surface area is the total surface. So first, find each surface...two triangles, same size and three rectangles, same size.
So you will have to add each....triangle+triangle+rectangle+rectangle+rectangle.
Area of a triangle = 1/2(b)(h) with b=base and h=height
Plug in knowns 1/2(15)(13)=A
Multiply 15X13=195 Then divide by 2. 195/2=97.5
The area of each triangle is 97.5 yd.
Area of a rectangle = (L)(W) with L=Length and W=Width
Plug in knowns (15)(24)=A Now, multiply
15X24=360
The area of each rectangle is 360 yd.
We need to add two triangles for front and back. and three rectangls.
97.5+97.5+360+360+360=1275
Surface area is 1,275 yd.
