2,384,598 + 6,000,000 = 2,984,598
<h3>
Answer: a = 37, b=2 and c=2.</h3>
Step-by-step explanation: Given expression 7 + 9/4.
Let us simplify given sum of fractions by taking common denominator, we get

Common denominator is 4.
Therefore, multiplying top and bottom of 7/1 by 4, we get
.
We got same denominators,
So, combining top numbers, we get

We can read 37/4 as 37 divided by 4.
Therefore, 37 ÷ 4.
Let us write 4 as the power of 2.

37 ÷ 
On comparing c÷a^b and 37 ÷ 2^2, we can see..
<h3>a = 37, b=2 and c=2.</h3>
Answer:
m<ABC = 71°
Step-by-step explanation:
Given:
m<BCA = 71°
x = 31 cm
y = 50 cm
Required:
m<ABC
Solution:
First, find AB, using Cosine Rule:
AB² = x² + y² - 2xy*Cos m<ABC
Plug in the values
AB² = 31² + 50² - 2(31)(50)*cos 71
AB² = 3,461 - 1,009.26128
AB² = 2,451.73872
AB = √2,451.73872
AB = 49.5150353 ≈ 50 cm
✔️Since AB ≈ 50 cm, and AC is also 50 cm, it means the triangle is an isosceles triangle.
Therefore, the base angles of ∆ABC, <ABC and <BCA, would be congruent.
Therefore,
m<BCA = m<ABC = 71°
m<ABC = 71°
