Answer:
D
Step-by-step explanation:
Using trigonometric ratios in the right triangle
tan45° = 1 and cos45° =
tan45° = =
Multiply both sides by 7
7 × tan45° = b, that is
b = 7 × 1 = 7
--------------------------------------------------------
cos45° = =
Multiply both sides by a
a × cos45° = 7, that is
a × = 7
Multiply both sides by
a = 7
We can see that the statements that about the figure that must be true in the following:
- ∠ABC is bisected by ray BD.
- BC = One-half of AC
- 2 ∠DBC = ∠ABC.
<h3>What is angle?</h3>
An angle actually refers to the figure that is formed when two rays share a common endpoint that is called vertex. Also, when two planes intersect, they also form angles.
Thus, we can see that the above options are the three options that makes the figure true.

Answer:
y-5=1/4(x-3)
Step-by-step explanation:
first you need to find the slope.
5-7 over 3-6 = -1/-4 or 1/4
next put into point-slope form.
y-y1=m(x-x1)
or y-5=1/4(x-3)
Answer:
b+6
Step-by-step explanation:
3b-2b+6=(3-2)b+6=b+6
6[5x(41-36) - (8+14)]
6[5x(5) - 22]
6[25x - 22]
150x - 132
