Answer:
Step-by-step explanation:
I believe the word phrase would look like this:
2 times the sum of 18 and t.
The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
Answer:
C. 
Step-by-step explanation:
Recall: SOHCAHTOA
Thus,
Reference angle = 28°
Adjacent = 15
Hypotenuse = 17
Plug in the values
Answer:
x=14
Step-by-step explanation:
This is asking for the ratio of A to B.
The x-10 is 1.
The 28 is 7.
Find the scale factor by executing 28/7=4.
So, you would want polygon A to be 4 in order to be proportional to polygon B.
Now, you can just guess and check that 14-10=4
Or, you can set up the equation as follows: x-10 = 4
+10 +10
x = 14 is your answer.
