First you need the size of an angle QPR = B = 180° - 123°
Lenght of QP = 10cm
QR = x
QP = r
x² = r² + r² - 2r² × cosB
Answer:
So the Solution is

Step-by-step explanation:
Solve for x: 4|2x − 2| + 10 = 34.
Step 1. Subtracting 10 on both the sides we get

Step 2. Dividing both the side by 4 we get

Step 3. Removing Modulus sign we get two values

So the Solution is

Answer:
C - 8
Step-by-step explanation:
Answer is in the picture:
Answer: C) x = 2
2^{2x + 2} = 2^{3x}
Since both terms (above) have the same base, set the exponents to be equal:
2x + 2 = 3x (Rearrange to solve for x)
x = 2
∴ x = 2
