Solve for x. Round your answer to the nearest tenth if necessary. NO SCAMS OR LINKS PLEASE ANSWER IS NOT 14.1 ​

Step-by-step explanation:

The triangle has a small square in the corner representing a 90 degree angle. This is a right triangle so we can use the Pythagorean Theorem to solve for the sides.

In this equation, a and b are the legs and c is the hypotenuse.

x and 8.5 are the legs because they make up the right angle. 11.2 is the hypotenuse because it is opposite the right angle.

Substitute the values into the formula.

Solve the exponents.

Solve for x by isolating the variable. 72.25 is being added, so we subtract 72.25 from both sides because subtraction is the inverse operation of addition.

x is being squared, so we take the square root of both sides.

Round to the nearest tenth. The 9 in the hundredth place tells us to round the 2 up to a 3.

The unknown side, x, is approximately 7.3

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

the answer is d
