Step-by-step explanation:
first do the triangle : 11 times 6 divided by 2 equals
33
the formula for a triangle is base times height divided by 2
now multiply 33 x 2 = 66because there is another triangle at the back.
now do 6 x 8 to find the sides that equal to 48
do 48 x 2 because there are 2 sides
now do the base : 11x8 = 88
for final step add all the answers together
66 + 48 + 88 answer is =
202
PLEASE MARK BRAINLIEST I PUT IN ALOT OF TIME FOR This
Hope it helps :)
Supplementary = 180 degrees...
A + B = 180
3x + 12 + 7x + 38 = 180
10x + 50 = 180
10 x = 130
x = 13
To find the A just substitute x in...
3 ( 13) + 12
A = 51
To check substitute the x..
A + B = 180
3(13) + 12 + 7(13) + 38 = 180
51 + 129 = 180
180 = 180
Answer:
using the foil
Step-by-step explanation:
you always have to get rid of the x for example if it is +3x you add it on to get rid of it and you carry on until you have solved x.
