Answer:
25%
Step-by-step explanation:
so out of 32 marbles, 8 of them are red. This means the rest are blue which is 24 blue. To make a percentage, all you do is make a fraction. out of 32, 8 were red so 8/32. Fractions are basically division so 8/32 is 0.25. This means 25%.
Here's the key to unlock the whole problem and make it crumble in a pile of dust at your feet:. A tangent is perpendicular to the radius at the point where the tangent touches the circle. /// Connect point O to the point way outside, and you have two congruent right triangles face to face. The angles inside each one add up to 180. Each angle at O is half of 134, and each angle at the point way outside is half of 'x'. I bet you can do it now.
Answer:
10a -7b
Step-by-step explanation:
9a-6b+a-b
Combine like terms
9a+a -6b-b
10a -7b

Supplementary means that the two angles, when put together, make a straight line (or 180 degree angle), so let's work this out.
A. The measure of angle 1 = the measure of angle 2: We know this is incorrect, just from looking at the picture, so let's cross that off.
B. The measure of angle 2 = the measure of angle 3: Angle 1 and angle 3 have the same measure, so since angle 2 isn't = to angle 1, angle 2 wouldn't be = to angle 3. Let's cross that off also.
C. Complementary means that the two angle put together make a 90 degree angle, but since angle three is already obtuse (more than 90 degrees), this answer is incorrect.
D. This answer is definitely correct! Angles 1 and 2 are supplementary, and angle 1 is equal to angle 3, therefore, angles two and 3 are also supplementary.
D. Is the correct answer!
