Think of the contents of the bag having 6 equal parts (in numerical quantity). Then the fraction of all the marbles which happen to be white marbles is 1/6. This converts to 16.67%.
Answer:415
Step-by-step explanation:
Angle DBE + Angle CBE = 90°
(0.1x-22)° + (0.3x-54)° = 90°
(0.4x - 76)° = 90°
(0.4x)° = 166°
x= 1660/4 = 415
(0.1 415 - 22)° + (0.3 415-54)° = 90°
41.5 - 22 + 124.5 - 54 = 90
166 - 76 = 90
Answer:
C
Step-by-step explanation:
NQP is a triangle. It has 3 angles given.
We know
<em>sum of 3 angles in a triangle is 180 degrees</em>
<em />
We are Given:
∠N = 2x
∠Q = 2x + 2
∠P = 134
THus, we can write and solve for x first:
∠N + ∠Q + ∠P = 180
2x + 2x + 2 + 134 = 180
4x + 136 = 180
4x = 180 - 136
4x = 44
x = 44/4
x = 11
Now, measure of ∠NQP is 2x + 2, so substituting the value of "x", we have:
2x + 2 = 2(11) + 2 = 22 + 2 = 24 degrees
So,
∠NQP = 24°
