D) The measures of the non- right angles in each triangle .
Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings
Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.
Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.
The answer is 7.
Look at the x=8 and then look up the y-value.
The graph passes (8,7) so therefore when x = 8 the y is 7
You have to set up a proportion so 2 over 3= x over 60. So multiply 2 times 60= 120 divided by 3 which is 40
Answer:
Step-by-step explanation: Identify the angle relationships, set up the equation that will yield the unknown value, solve the equation for the unknown value, substitute the answer to determine the measurement of the angles then, check and verify your answer by measuring the angle with a protractor.
