Answer:
3) B) 90°
4) A) 75°
Step-by-step explanation:
3) interior angles of a triangle =180°
So
40+50+?=180
? =180- 90
? =90
4) same rule
40+65+?=180
? =180 - 105
? = 75

Be glad to tell me if it’s correct or not
Answer: 12πins.
Step-by-step explanation:
Since the area if a circle = πr²
From the question
Area of the circle = 36πins²
To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.
πr² = 36π, solving this gives. Divide through by π
r² = 36
r = +/-√36
= +/-6
Now to find the circumference of the circle, we substitute for r in the formula below.
Circumstances = 2πr
= 2 ×π × 6
= 12πins.
