Answer: 11 degrees
Step-by-step explanation:
Complementary means 2 angles that add up to 90 degrees.
90 degrees - 79 degrees = 11 degrees
Double Check: 79+11 = 90 degrees
Okay. So, using the scale, we can solve for the length of the actual boat by writing and solving a proportion. Let’s write it out like this: 1/6.5 = 7.5/x. This is because you’re looking for the real length of the boat, so the x would be lined up horizontally with 6.5, as shown in the proportion. Let’s cross multiply. 6.5 * 7.5 is 48.75. 1 * x is 1x. 48.75 = 1x. Now, let’s divide each side by 1 to isolate the “x”. When you do that, you get x = 48.75. There. The length of the actual boat is 48.75 feet.
I’m going to go with A, because it seems they all meets the definition of congruent
