Answer:
linear
Step-by-step explanation:
∠C is 148°.
Step-by-step explanation:
- Step 1: Given ∠A = 16° and ∠B = (10x - 64)°. Also, AC = BC. Now, the angles opposite to equal sides of a triangle are equal. So ∠B = 16°
- Step 2: Sum of angles of a triangle is 180°
⇒ 16° + 16° + ∠C = 180°
⇒ ∠C = 180 - 32 = 148°
Answer:

Step-by-step explanation:
Given: Equation is 
To find: flaw in Gwendolyn's work and the correct solution to the equation.
Solution:
In the given question,
the first step is 
The second step is 
(This step is obtained on multiplying
by
)
The third step is 
This step is wrong as on transposing 12 from left side of the equation in the second step to the right side, the following equation is obtained:

So, the correct solution is
