Answer:
A =24.7° ; B = 40.6° ; C =114.7°
Step-by-step explanation:
Cosine Law
a² = b²+c²-2bc cos A
b² = c²+a² -2ca cos B
Sum of three angles of a triangle is 180°.
a = 34 ; b= 53; c = 74
Substituting the given values in the cosine law, we have
34² = 53² + 74² - 2*53 *74 * cos A
7844 cos A = 2809 + 5476 - 1156 = 7129
cos A = 7129/7844 = 0.9088
A = cos⁻¹ (0.9088) = 24.6600° = 24.7°
53² = 74² + 34² - 2 (74)(34) cos B
5032 cos B = 5476 + 1156 - 2809 = 3823
cos B = 3823/5032 = 0.7597
B = cos⁻¹ (0.7597) = 40.5622° = 40.6°
Also, A + B + C = 180°
24.7 + 40.6 + C =180
C =180 - 65.3 = 114.7°
∴ A =24.7° ; B = 40.6° ; C =114.7°

c. 6 people preferred giraffes than dogs.
Answer:
see below
Step-by-step explanation:
2*35-176+65/ 2
Following PEMDAS
Multiply and divide from left to right
2x35-176+65/ 2
70 -176+65/ 2
70-176+32.5
Then add and subtract from left to right
-106 +32.5
-73.5
or
(2*35-176+65)/ 2
Following PEMDAS
Parentheses first
Multiply and divide from left to right
(70 -176+65)/ 2
Then add and subtract in the parentheses
(-41)/2
-21
