Answer:
90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,
90 - 37

Answer:
A ≈ 1900.7 m²
Step-by-step explanation:
The area (A) of the race track is
area of outer circle - area of inner circle
= πR² - πr²
= π × 63² - π × 58²
= π (63² - 58² )
= π(3969 - 3364)
= π × 605
≈ 1900.7 m² ( to 1 dec. place )
