Answer:
A=1/2h(7+11) or A=1/2h(77)
The area is dependent on the height and the height changes based on the length of both of the bases
Step-by-step explanation:
Answer:
70 ft.
Step-by-step explanation:
If 1 in = 10 ft. that would mean your 7 inches would be multiplied by 10 to give you 70 ft. Have a good day :)
Answer:
115 degrees
Step-by-step explanation:
We know that all the angles of a triangle add up to 180 degrees.
Therefore 7x+10+x+20+2x=180
Combine like terms
10x+30=180
Subtract 30 from both sides (subtraction property of equality)
10x=150
Divide both sides by 10 (division property of equality)
x=15
Now we can plug this into the largest angles equation.
7(15)+10
= 115 Degrees.
Answer:
91
Step-by-step explanation:
Each term is 8 more than the last, so you can write the terms of the sequence until you get there:
11, 19, 27, 35, 43, 51, 59, 67, 75, 83, 91
__
Or, you can use the formula for the general term of an arithmetic sequence. You have first term a1=11 and common difference d=8.
an = a1 +d(n -1)
a11 = 11 + 8(11 -1) = 11 + 80
a11 = 91
