Answer:
74
Step-by-step explanation:
A polygon's angles add up to (n-2)*180, where n is the total number of sides, and a hexagon has 6 sides, which means its angles add up to 720 degrees.
Therefore, we can set up an equation where the missing angles, marked as x, and the rest of the angles add up to 720:
x+x+152+108+140+172=720
2x+572=720
2x=148
x=74
Therefore, the angles of the 2 missing angles is 74
The correct answer would be 48 min. (Choice B)
In an inverse relationship, we multiply the 2 variables together to get a constant.
Our equation would be:
GT = C If we plug in the numbers we have:
8(12) = 96
Now, lets solve the equation for T when G is 2.
2T = 96
T = 48
Answer:
5.75
Step-by-step explanation:
322/56=5.75
so the answer would be 5.75 or rounded up to 6
Answer:
<h2>D. 18</h2>
Step-by-step explanation:
We know:
1. Diagonals of a rhombus are perpendicular.
2. Diagonals divide the rhombus on four congruent right triangles.
3. The sum of measures of acute angles in a right triangle is equal 90°.
Angles CAD and ACB are alternate angles. Therefore they are congruent:
m∠DAC = m∠ACB ⇒ m∠ACB = x°.
From 3. we have the equation:
(5x - 18) + x = 90
(5x + x) - 18 = 90 <em>add 18 to both sides</em>
6x = 108 <em>divide both sides by 6</em>
x = 18
