Answer:
The final angle would be 351
Step-by-step explanation:
All quadrilaterals have interior angles that add up to 360. So to find the remaining angle, we have to subtract each of these numbers from 360.
360 - 4 - 3 - 2 = 351
Answer:
Ans 1. 
Ans 2.a.

Ans.2.b.

Step-by-step explanation:
Solution:
1.
Vertically opposite angles are equal.

2.a.
proof for Δ BAC ≅ ΔKJL by SAS postulate.
InΔ BAC and Δ KJL
BA ≅ KJ Given
∠ BAC ≅ ∠ KJL {measure each angle is 90}

2.b.
proof for Δ BAC ≅ ΔKJL by HL theorem.
InΔ BAC and Δ KJL
BA ≅ KJ Given
∠ BAC ≅ ∠ KJL {measure each angle is 90}

Answer: - 6 1/2
Step-by-step explanation:
We should note that:
=-4 - 2 1/2
= -6 1/2
For example, let's assume you owe Bob $4 and then you owe Bill $2 1/2. To calculate the total amount owed, you would have $6 1/2.
Looks like the equation is

Substitute
, so that
. Then the equation is the same as

Integrate both sides to get

Given that
, we have

so the solution is
