Since we know that 1 foot is 12 inches, we can determine that a half of a foot is 6 inches. We have 7 feet, so we need to multiply 12 and 7 to find 7 feet in inches. 12*7 is 84, but we still have to add in our additional 6 inches. When we add 6 to 84, we get 90. Therefore, the classroom door is 90 inches tall.
Step-by-step explanation:
1.8(2/7x)15
1.8×15(2/7x)
27(2/7x)
54/7x
Answer:
Believe it or not, X is 0!!!!!!!!!!!
You didn't put the choices
The sum of all the angles of any triangle is 180 degrees
--> Therefore the missing angle is:
<u>x = 180 - 60 - 75 = 45</u>
Hope that helps!
