What is the solution to the equation –10.3+y = 5.2?

quester [9]

-10.3 + y = 5.2

First, regroup the terms. / Your problem should look like: $y - 10.3 = 5.2$
Second, add 10.3 to both sides. / Your problem should look like: $y = 5.2 + 10.3$
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like: $y = 15.5$

Answer: y = 15.5 (D)

What are the angle measures of triangle ABC?

Schach [20]

The angle measures of triangle ABC is ∠A=90°, ∠B= 60°, ∠C = 30°. Thus, the correct option is B.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

As it is known that the angles of the triangle are 30°, 60°, and 90°. Therefore, the largest angle is 90° which will be the opposite of the largest side of the triangle, therefore, the measure of ∠A=90°.

Also, the shortest angle of the triangle is 30°, which will lie at the opposite of the smallest side of the triangle, therefore, the measurement of the ∠C=30°.

Now, the angle left is ∠B therefore, the measure of ∠B=60°.

Hence, the angle measures of triangle ABC is ∠A=90°, ∠B= 60°, ∠C = 30°. Thus, the correct option is B.
