PLEASE HELP THANK UU

A: 90° B: 67° c: 23°  D: 67°  E: 90°  F: 23°

Step-by-step explanation:

A: 90°  known

B: 67°   90-∠C=90-23=67

C: 23°   known

D: 67°   similar triangle property

E: 90°   known

F: 23°   similar triangle property

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

can you complete your sentence? i could !
