Answer:
6 ft
Step-by-step explanation:
A=1/2bh. To find the area of the triangle, we subtract the area of the rectangle from the total. Which would be 108 - (12x6) = 36. Now we have the area. So, 36 = 1/2bh. "b", the base is 12. So we solve for h. h = (36x2)/12 or h = 36/6, which both equal 6.
Both angles equal 73, according to the vertical angle conjecture. To solve for x:
(1+2x)=73
2x=72
x= 36
Answer:
Step-by-step explanation:
Everything is correct. But you forgot to add
x = 6 - square root of 26. The answer is
x = 6 + square root of 26 or
x = 6 - square root of 26
Answer:
4th answer.
Step-by-step explanation:
I'M NOT 100% SURE (I just learnt that so yeah)-
Answer:
ENGLISH SYSTEM:
What you want to do is simply convert the feet into inches for 1a. and for 1b. add the inches to the length and the width. For the rest of the English system, what you have to do is plug in the numbers.
METRIC SYSTEM:
So for this one it is the same thing but different measurements. Instead of converting feet to inches, you are converting meters to centimeters. Follow the same steps as you did with the English system.
Step-by-step explanation:
1a.
13*12=156
18*12=216
1b.
156+6=162
216+9=225
2.
162*225=36,450
3.
3.75*8=30
4.
36,450/30=1,215
1a.
4*100=400
5*100=500
2.
400*500=200,000
3.
9.5*20=190
4.
200,000/190≈1,053
