Triangle Abc is right triangle, and the measure of angle A is 28 percent what are the measure of two angles

2 answers:

If one of the angles is 28 degrees, then another is 90 degrees. Subtract 90 and 28 from 180 to get the final measurement. The last angle would be 62 degrees

The other two angles are each 76 degrees because a triangle has 180 degrees total minus the 28 divided by the two angles left.

In ΔRST, r = 210 inches, t = 550 inches and ∠T=166°. Find all possible values of ∠R, to the nearest degree.

valkas [14]

Answer:

m(∠R) = 5°

Step-by-step explanation:

By applying sine rule in the given triangle RST.

$\frac{\text{sin}(\angle R)}{ST}= \frac{\text{sin}(\angle T)}{SR}$

$\frac{\text{sin}(\angle R)}{r}= \frac{\text{sin}(\angle T)}{t}$

$\frac{\text{sin}(\angle R)}{210}= \frac{\text{sin}(166)}{550}$

sin(∠R) = $\frac{210\times \text{sin}(166)}{550}$

= 0.09237

m(∠R) = $\text{sin}^{-1}(0.09237)$

= 5.3°

≈ 5°

Akio found 18 cents in his pocket. He found 6 more coins in his pocket. Altogether he has 73 cents. What were the 6 coins he fou

Dafna1 [17]

Answer:

1 quarter, 1 dime, and 4 nickels

Step-by-step explanation:

First you subtract the 18 cents that were found in the pocket from the total amount of 73 cents to get the total amount of the 6 other coins:

73-18=55.

So the total amount of the 6 coins equals 55 cents.

The quarter = 25 cents

The dime = 10 cents

The 4 nickels = 5 + 5 + 5 + 5 = 20

1 quarter, 1 dime, and 4 nickels add up to the necessary total of 6 coins and when you add up the total cents of the quarter, dime, and nickels, 25 + 10 + 20 it comes to the sum of 55, which is how much the 6 coins are worth in total.

So therefore, the answer is 1 quarter, 1 dime, and 4 nickels.
