Answer:
38.9°
Step-by-step explanation:
The three angles in a triangle add up to 180°. Also, a right triangle has a right angle in it. A right angle is 90°.
90° + 51.1° + x = 180°
141.1 + x = 180°
subtract 141.1°
x = 38.9°
Answer:
13013
Step-by-step explanation:
Express each number in terms of the product of prime numbers.
91 = 7 × 13
143 = 11 × 13
169 = 13 × 13
Now consider the maximum number of times each factor occurs for each number.
The factor 7 occurs once
The factor 11 occurs once
The factor 13 is repeated twice ( maximum number of times for 1 number )
Thus LCM = 7 × 11 × 13 × 13 = 13013
It would be 1.63 because if you multiplied it by 5 you would get 8.15
