You can use the Pythagorean Theorem:
a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)
So the equation is 2x^2=98 (simplest form) and x=7

Answer:
90
Step-by-step explanation:
The angle formed outside = 1/2(difference of intercepted arcs)
The large arc is 360-x and the inner arc is x
x = 1/2 (360 -x - x)
x = 1/2 (360 -2x)
Multiply each side by 2
2x = 360 -2x
Add 2x to each side
2x+2x = 360
4x= 360
Divide by 4
4x/4 = 360/4
x = 90
Answer:
33
Step-by-step explanation:
To find the mean of 5 numbers, you add the 5 numbers and divide by 5.
Let the unknown number = x.
(27 + 42 + 43 + 35 + x)/5 = 36
(x + 147)/5 = 36
x + 147 = 180
x = 33
Answer: 33
Answer:
87 degrees
Step-by-step explanation:
9x+6 + 7x-2 = 148
16x+4 = 148
16x = 144
x = 9
Plug into 9x+6
9(9)+6 = 87
