Any line is 180 degrees, so z is 67 degrees and x is 6.
Answer:
x = 3.5 ; y = -1.5
Step-by-step explanation:
Answer:
the answer is A. 2370 sq. in
Step-by-step explanation:
area of the triangles first
A = 1/2 ad
a = (45 in) (20 in)
a = 1/2 (900 sq in)
a = 450 sq in
***remember to multiply 450 * 2 because you have 2 triangles***
Total area of both triangles is 900 sq. in.
Find the area of the 3 rectangles A = LW
1st rectangle and 2nd rectangle
a = cb
a = (30 in) (14 in)
a = 420 sq in. (make sure you add this again in the Total Surface area)
3rd rectangle
a = ab
a = (45 in) (14 in)
a = 630 sq. in
Total Surface area = 2 (1/2 ad) + 2(cb) + (ab)
= 2 (450 sq. in) + 2 (420 sq. in) + 630 sq. in
= 900 sq. in + 840 sq. in + 630 sq. in
= 2370 sq. in
