Answer:
71 degrees
Step-by-step explanation:
please someone help me with this ASAP especially with the workout!!
From the triangle shown;
YX² = YZ² + XZ² - 2(YZ)(XZ) cos Z
28² = 25² + 23² - 2(25)(23) cos Z
784 = 625 + 529- 1150 cos Z
784 - 1154 = -1150cos Z
-370 = -1150cos Z
cos Z = 370/1150
cos Z = 37/115
cos Z = 0.3217
Z = arccos 0.3217
Z = 71.23
hence the measure of <Z is 71 degrees
a bus took 30
minutes-------------------------- to cover a distance of 20 city blocks<span>
X
minutes------------------------------------------------one (1) city block</span>
I apply a rule of three
<span>
X=(1)*(30)/20=1.5 </span>
Therefore
the bus moved
1.5 minutes/block city
