Answer:
x=12.727822
Step-by-step explanation:
Since we know two of the angles, we can find the third. 180-90-45=45. This means the two sides of the triangle are also equal, and we know the hypotenuse is 18. So we can use the Pythagorean theorem.
x²+x²=18²
2x²=324
x²=162
x=√162
x=12.727822
The simplified version of this equation is 14.2+-5a. Hope I helped

Answer:
2/3 ( 8 + y ) + 4 r
Step-by-step explanation
2/3 is the two thirds
The sum of 8 and y is 8 + y
So, two thirds of the sum of 8 and y is 2/3 ( 8 + y )
Then, the product of 4 and r is 4 r
Therefore; Two-thirds of the sum of 8 and y plus the product of 4 and r is 2/3 (8 + y) + 4 r
