Answer:
X = -8
Step-by-step explanation:
-7(x-5)=91
x-5=-13
x=-13+5
x=-8

I really hope this helps :D
Hi there!
3c + 2d = 2 for d = 4
3c + 2(4) = 2
3c + 8 = 2
Subtract 8 to both sides
3c + 8 - 8 = 2 - 8
3c = -6
Divide both sides by 3
3c/3 = -6/3
c = -2
I hope I helped!
Answer:
About 10.4 cm
Step-by-step explanation:
By the Law Of Sines:
![\dfrac{6}{\sin 30}=\dfrac{b}{\sin 120} \\\\\\b=\dfrac{6}{\sin 30}\cdot \sin 120\approx 10.4\text{ cm}](https://tex.z-dn.net/?f=%5Cdfrac%7B6%7D%7B%5Csin%2030%7D%3D%5Cdfrac%7Bb%7D%7B%5Csin%20120%7D%20%5C%5C%5C%5C%5C%5Cb%3D%5Cdfrac%7B6%7D%7B%5Csin%2030%7D%5Ccdot%20%5Csin%20120%5Capprox%2010.4%5Ctext%7B%20cm%7D)

Answer:
Step-by-step explanation:
The rhombus has several relevant properties.
- The sides are all the same length
- Diagonals are perpendicular bisectors of each other
- Diagonals divide the rhombus into congruent triangles
The last of these relations can be used to find x:
7x° = 35°
x = 35°/7° = 5
The second of the relations can be used to find y:
3y° = 90°
y = 90°/3° = 30
The first of the relations can be used to find z:
10z -8 = 5z +32
5z = 40 . . . . . . . . . add 8-5z
z = 40/5 = 8
