Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° = 
= 
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x = 
≈ 61.8 ( to the nearest tenth )
No
for example (question 1),
3(2a - 5) you multiply the numbers inside the parenthesis ().
so it will be 6a - 15
And if there is a negative number in front of the parenthesis, you multiply that too
-1(2x-5) will be -2x+5
negative times negative will be positive!
1. Is a right angle
2.is a obtuse.
B=29/18 or B=1.61 or B=1 11/18
Answer:
The slope of a line is measured in the change in y divided by the change in x with 2 points on the same line.
For example, if a line crosses both points (2, 3) and (6, 14) that means the slope would be the change from 3 to 14, which is 11, divided by the change from 2 to 6, which is 4, or 11/4.
Hope this helped!
