Answer:
b=√3
a=2
Step-by-step explanation:
Since you are given one side and an angle, you can immediately think of using cos, sin, and tan
When solving for b, you would set up your equation with tan30=1/b since tangent is opposite/adjacent
Next for a, you would solve for sin30=1/a since sine is opposite/hypotenuse
Hope this helps! :)
Answer:
3.8
Step-by-step explanation:
Hey! Let's start by assuming that these are all normal courses, and that <u>GPA is given by the following scale:</u>
A - 4.0
B - 3.0
C - 2.0
D - 1.0
F - 0.0
That said, this question really just involves calculating the averages.
To find the average, we add all the values together and divide the sum by the total number of values.
<u>Therefore, our expression would look like:</u>
(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5
This is because there are 5 total values.
Simplify:
19/5
3.8
This means your GPA would be 3.8
Answer:
i think is 3/2. im no really sure
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA =
cosA = -0.275
A =
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
