Answer:
C. always true
Step-by-step explanation:
<1 and <4 from a straight line and a straight line is always 180 degrees so
If the formula is V= Ab x H
then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.
Answer:
x = 20
Step-by-step explanation:
Adjacent angles on straight line add up to 180º
7x + (x + 20) = 180
7x + x + 20 = 180
8x + 20 = 180
8x = 160
x = 20
Answer:
2.25 inches
Step-by-step explanation:
400+400 is 800 then 1/4 is .25 so that would make it 100 out of the 400 add that to 800 = 900 so its 2.25 inches
