Answer:
∠A = 45°
Step-by-step explanation:
The sum of angles in a triangle = 180°.
That means in the triangle ABC, ∠A + ∠B + ∠C = 180°.
Given ∠B = 90° and ∠C = 45°.
⇒ ∠A + 90° + 45° = 180°
⇒ ∠A = 180 - 90 - 45
⇒ ∠A = 45° is the required answer.
Answer:
a)
b)
c)1945 > 45
d) 1921 >5/7, 13/14
Step-by-step explanation:
a) 56 and 29/36
⇒ 56 > 0.80
or,
b) 5/12 and 3
⇒ 3 > 0.41
or,
c) 25 and 1945
Here, 1945 > 45
d) 5/7, 13/14, and 1921
⇒ 1921 > 0.71 and 0.92
or, 1921 >5/7, 13/14
