May someone me with these questions. it’s urgent!

1:

a= 1/2

b= 1

c= 1

d= 1/2

2: 1/3

3: they did not beat the record, their time was 3 minutes

Step-by-step explanation:

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
