∠A = 24°
∠B = 87°
∠A = 24°
Explanation:
The sum of angles in a triangle is 180 degrees
let measure of angle A = ∠A
∠B = 15 more than three times the measure of angle A
∠B = 15 + 3∠A
∠C = 45° more than the measure of angle A
∠C = 45° + ∠A
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
∠A + 15 + 3∠A + 45° + ∠A = 180
collect like terms:
∠A + 3∠A + ∠A + 15 + 45 = 180
5∠A + 60 = 180
5∠A = 180 -60
5∠A = 120
∠A = 120/5
∠A = 24°
∠B = 15 + 3∠A = 15 + 3(24)
∠B = 87°
∠C = 45° + ∠A = 45° + 24°
∠C = 69°
Answer:
3x+4x+7
Step-by-step explanation:
First, a Trinomial consists of three terms.
so we have <u>blank</u>+<u>blank</u>+<u>blank</u>
Next we need to add the coefficients.
<u>3</u>+<u>4</u>+<u>blank</u>
Add the variables.
3x+4x+<u>blank</u>
And lastly, add the constant.
3x+4x+7
Good luck!
The absolute value parent function.
Answer:
<h2><u><em>
32</em></u></h2>
Step-by-step explanation:
Assuming that the question is:
12 * (3 + 2^2) : 2 - 10 = remember PEMDAS
12 * (3 + 4) : 2 - 10 =
12 * 7 : 2 - 10 =
84 : 2 - 10 =
42 - 10 =
<u><em>32</em></u>
