Answer:
16 and 82 degrees
Step-by-step explanation:
You can sum all of the angles together and solve for x.
(x - 1) + (5x - 3) + (5x - 3) = 180
11x - 7 = 180
11x = 187
x = 17
The first angle is 16 degrees. (17 - 1)
The other two angles are 82 degrees(5(17) - 3)
Answer:
Step-by-step explanation:
x²+x²=9²
2x²=81
x²=81/2=(81×2)/4
x=9√2/2≈4.5√2≈6.36
9.
x²+x²=11²
2x²=11²
x²=11²/2
x=11/√2=11√2/2≈7.78
In the first problem you are given a formula (y = 3x), along with a table.
From the data in the table, find the slope of the linear equation that relates x and y in that data.
Then compare the two slopes. Which is the greater? the smaller?
17. (x^2-x+3)(4x+1)
18.(x+2)(x) - (7)(3)
Answer:
Step 2(1-(-1)=0),-2.2
Step-by-step explanation:
Step 2: 1-(-1)=0 is wrong it should be 2
1-(-1)=1+1=2
The correct solution is -2.2
