Which is the converse of the conditional statement? A-If an angle does not measure between 0° and 90°, then it is not acute.
B- If an angle measures between 0° and 90°, then it is acute.
C-If an angle is acute, then it measures between 0° and 90°.
D-If an angle is not acute, then the angle does not measure between 0°
and 90°.

28

step-by-step explanation:

because that's the answer

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

the answer to question 1 is -8, 28.
