What is the measures of the complement and supplement of an angle that measures 35°
vazorg [7]

Answer:

Complement: 55°

Supplement: 145°

Step-by-step explanation:

<em>Complementary </em>angles are any two angles which sum to 90° (a right angle); <em>supplementary </em>angles sum to 180° (a straight angle).

35 + 55 = 90, so 55° is the <em>complement </em>to 35°, while 145° is the <em>supplement, </em>since 35 + 145 = 180.

In Game 1, Emerson struck out 30 times in 90 times at-bat. In Game 2, he struck out 40 times in 120 times at-bat. In Game 3, Eme
Anna71 [15]

Answer:

32% of the times at-bat.

Step-by-step explanation:

Since in Game 1, Emerson struck out 30 times in 90 times at bat; in Game 2, he struck out 40 times in 120 times at bat; and in Game 3, Emerson struck out 42 times in 140 times at bat; To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:

\frac{(30+40+42)}{(90+120+140)}=x

\frac{112}{350} =x

0.32=x

Therefore he actually hit the ball 32% of the time.
