beks73 [17]2 years ago
6 0

Answer:

a=35°

b=55°

c=110°

Step-by-step explanation:

∡a=35° because they are opposite angles by the vertex

∡a +∡b+90°=180° (by definition of internal angles of a triangle)

35°+∡b+90°=180°

∡b=180°-90°-35°

∡b=90°-35°

∡b=55°

∡c+70°=180 because they form a straight angle

∡c=110°

Five swimmers entered a competition. Four of the swimmers have had their turns. Their scores are 10.8s, 10.75s, 10.79s and 10.81
Shalnov [3]

Answer:

10.74s or faster (lower)

Step-by-step explanation:

The lowest time out of all of them is 10.75, so to all the 5th swimmer needs to do to win is to undercut the swimmer who got 10.75s by a 100th of a second. i.e 10.74s or faster (lower) would win.

What is the measure of Angle B
patriot [66]

Answer:

119

Step-by-step explanation:

Angle C= 62

So you add 62 + 57 which gives you 119

All angles must add up to 180 so you subtract 119 from 180 which gives you 61

Since angle A is 61 and a straight line angle is 180 you subtract 61 from 180 to give you angle B

180 - 61 = 119

therefore your answer is 119
