Answer:
We need to know angle C which is (180 -123 -34) = 23°
We'll use the Law of Sines
Sine (A) / side a = Sine (B) / side b
Sine (34) / 10 = Sine (123) / side b
0.55919 / 10 = 0.83867 / side b
10 * .83867 / .55919 = side b
side b (or line AC) = 14.998
Step-by-step explanation:
Answer:
z = 0
Step-by-step explanation:
Step 1: Write equation
9z - 5 - 4z = -5
Step 2: Solve for <em>z</em>
- Combine like terms: 5z - 5 = -5
- Add 5 to both sides: 5z = 0
- Divide both sides by 5: z = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 5 - 4(0) = -5
0 - 5 - 0 = -5
-5 = -5
M(<Q) = 90; m(<P) = 12; m(<x) = 180 - 90 - 12 => m(<x) = 78. a.
I think the answer is 3cm I’m not 100% sure
