The acute angles of a right triangle are in the ratio of 7:11. Find the measure of each angle.

A) 25, 65, 90

B) 35, 55, 90

C) 25, 155

D) 35, 145

B

Step-by-step explanation:

Since it's a right angle triangle, one angle has to be 90.

Total angle in a triangle = 180

Other two should add up to 90.

7/18 × 90 = 35

11/18 × 90 = 55

Tbe angles are 35°, 55° and 90°

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore measures of acute angles will be 7x and 11x.

Hence, measure of each angle of right triangle are 35°, 55°, 90°.

Thus, option B is the correct answer.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
