Answer:
A) 96
Step-by-step explanation:
The 2 base angles are both 42* thus adding up to 84*. 180-84=96
You are welcome.
Answer:
I think that 110 would be the correct answer. PLEASE correct if I'm wrong.
Step-by-step explanation:
See, a 90 degree angle is a right angle or like one of the ways you can split a square in half. l
So since that is a little more than a 90 degree angle, I would guess it would be 110.
Answer:
36 sq. cm
Step-by-step explanation:
triangle area= 0.5 * 12* 10
rectangle are= 8* 3
60 - 24 = 36
Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
Area of Parallelogram= base * height
A= (12 3/4)(2 1/2)
A= (51/4)(5/2)
A= 255/8
A= 31 7/8
OR
A= (12.75)(2.5)
A= 31.875
Hope this helps! :)
