Answer:
Let x = the measure of the smaller angle
Let 3x + 40 = the measure of the larger angle
x + 3x + 40 = 180
4x = 140
x = 35º
3x + 40 = 3(35) + 40 = 145º

Hello!
Question 1
In a 30-60-90 triangle the hypotenuse is 2x the height is

and the base is x
Find x
11 = 2x
Divide both sides by 2
5.5 = x
Put in x into the other equations

x = 5.5
2x = 11
11 + 5.5 + 9.5 = 26
We put the equations into a calculator and see which one is close to 26
The answer is B) 33/2 + 11/2 * the square root of 3

Question 2
For this one we can put the choices into a calculator and see what comes up close to 15
tan(86.19°) = 15.01
the answer is D) 86.19°
Hope this helps!
Km/h = 18,432 is the answer to your question.
Answer:
14.5
Step-by-step explanation:
10 + (2 x 3)2 ÷ 4 × (3 x 1/2)
10 + (6)2 / 4 * (1.5)
10 + 12 / 4 * 1.5
10 + 3 * 1.5
10 + 4.5
14.5
