a. Angles ABC and CBD are supplementary, so you know that
The interior angles of any triangle sum to 180 degrees in measure, so that .
By the law of sines, we then have
b. In triangle BCD, we have
and so
Answer:
0.87 > 0.17
3.97 < 6.63
8.04 < 8.9
Is that what ur looking for?
Step-by-step explanation:
Step-by-step explanation: If I replace the variables with the numbers, the equation would be: 36+(4x2x3)/36-(4x2x3). First, solve the numbers in the parentheses. Both numbers in the parenthesis equals 24 because 4x2 is 8 and 8x3 is 24. Then, 36+24/36-24. PEMDAS, so 24/36 is 0.666666666667. Then 36+0.666666666667 is 36.666666666667. Next, 36.666666666667 minus 24 is 12.666666666667.
4 and a half is 4.5, and if you divide 3 into that, you get 1.5.
Answer:
1.53
Step-by-step explanation:
3.35 - 0.8 = 2.55
2.55 - 1.02 = 1.53
