Using the law of sines:
Sin (angle) = opposite leg / hypotenuse
Sin(30) = 14 /x
x = 14 * sin(30)
x = 28
Answer:
x=-7 and y=4
Step-by-step explanation:
-4 times -7=28-4=24
Answer:
<XYZ = 117°
<XYW+ WYZ = 117°
(6x+44)+(-10x+65)= 117°
6x+44-10x+65= 117°
-4x+ 109= 117°
-4x= 117-109
-4x= 8
x= 8/-4
x= -2
<XYW= 6x+44= 6×-2+44= -12+44= 32°
<WYZ= -10x+65 = -10×-2+ 65= 20+65= 85°
Step-by-step explanation:
Answer:
all choices apply
Step-by-step explanation:
Angles are "adjacent" when they share a vertex and the ray between them. Thus the following pairs are adjacent:
- 90° and ∠A
- ∠A and ∠B
- ∠B and ∠C
- ∠C and 27°
- 27° and 90°
A linear pair is an adjacent pair in which the non-common rays point in opposite directions (lie on the same line). The angles of a linear pair total 180°, so are supplementary.
These pairs of angles are supplementary:
Vertical angles are not adjacent, but share a vertex and have sides that are opposite rays. They are supplementary to the same angle. here, angles A and C are a vertical pair.
All of the answer choices apply.
The answer is (-4,-4) because y has to equal x, the first -4 is the x and the second one is the y
