Using supplementary angles, it is found that the measure of angle x is of 65º.
<h3>What are supplementary angles?</h3>
Angles are called supplementary if the sum of their measures is of 180º.
In this problem, angles x, 25, and 90º are supplementary, hence:
x + 25 + 90 = 180
x = 180 - (25 + 90)
x = 65º.
The measure of angle x is of 65º.

There are 147 chocolates in the jar.
Candies = 9
Chocolates = 7
9 + 7 = 16
Candies = 9/16 = 0.5625 * 100% = 56.25%
Chocolates = 7/16 = 0.4375 * 100% = 43.75%
Total items = 336
Candies = 56.25% * 336 = 189
Chocolates = 43.75% * 336 = 147
Answer:
D
Step-by-step explanation:
The diagonals of a rhombus bisect the angles, thus
∠ ABC = ∠ CBD = 5x - 18 and
∠ BAC = ∠ DAC = x
The diagonals are perpendicular bisectors of each other, thus
the angles round the intersection of the diagonals = 90°
Consider the triangle on the left of the rhombus, then
5x - 18 + x + 90 = 180 ( sum of angles in a triangle )
6x + 72 = 180 ( subtract 72 from both sides )
6x = 108 ( divide both sides by 6 )
x = 18 → D
