<2 = 45 degrees They are corresponding angles
74 + <1 + <2 = 180 it makes a straight line
74 +<1 +45 = 180
119 +<1 =180
subtract 119
<1 = 180 -119
<1 = 61 degrees
Answer:
75 is 75% of 100
Step-by-step explanation:
Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.
Hope this helps :)
