It only has two number sentences because 81 divided by anything else wont work only 9 would. Also since 9 times 9 is equal to 81
You should just use so.crative or photo.math
Hello Melissamv9321, <span>find the lengths of the missing sides if side a is opposite angle a, side b is opposite angle b, and side c is the hypotenuse</span> <span>In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.</span>
Answer:
x = 4
Step-by-step explanation:
To begin, first find Angle SUT.
Knowing that SUH is a straight line, Angle SUT plus 100 degrees should equal 180 degrees. Angle SUT is 80 degrees.
The sum of all the degrees in a triangle is also 180 degrees.
SO
(4x + 4) + (21x - 4) + 80 = 180
25x + 80 = 180
25x = 100
x = 4
