Answer:
67.3km/h
Step-by-step explanation:
Find the amount of time it took from 10:12 to 11:18.
Which is 66 minutes.
Find the average speed.
Formula of average speed =
Total distance/time
Which is,
74/66 = 1.121 (recurring decimal)
1.121 x 60 = 67.26km/h
= 67.3km/h (Estimated to 1 dp)
Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
m∠bre + m∠bre = 90°
m∠bre = 45°
Then, for the relationship of bre and tap, we have the equation,
m∠bre + m∠tap = 180°
45° + m∠tap = 180°
m∠tap = 135°
The measure of tap is equal to 135°.
I think i’m not really good at math so..
