Answer:
Step-by-step explanation:
In ΔABC,
∠ABC + ∠BAC + ∠BCA = 180 {ANGLE SUM PROPERTY OF TRIANGLE}
41 + 102 + ∠BCA = 180
143 + ∠BCA = 180
∠BCA = 180 - 143
∠BCA = 37
∠CAE = ∠BCA {Alternate interior angles are equal}
x = 37°
Answer:
X25
Step-by-step explanation:
thank me later
The answer is
<span>(a−b)²+b²/a²
proof
if A is the area of the
</span><span>inner</span> squared, so A= c², and c²= (a−b)²+b²
so the side of the outer must be a-b +b=a, its area is a²
1/84
1/7 ÷ 12
turn 12 into 1/12 bc your dividing fractions and turn the division symbol to multiplication
1/7 × 1/12
answer: 1/84
