Answer:
tanA=34⟹sinA=332+42−−−−−−√=35
Now, we have
sinAcosA=tanA
⟹3/5cosA=tanA
⟹cosA=13×54×3
⟹cosA=45
⟹cosAsinA=4×35×5=1225

❖ The correct answer choice is D. 4/5.
0.8 as a decimal is 8/10
8/10 can then be reduced to 4/5.

Use the least common denominator(LCD) to solve this equation:
1 + (-2/3) - (9/2)
so, what is the LCM of 3 and 2 : 6
so, the LCD = 6
1 + (-2 x 2/6) - (9 x 3/6)
the 1 = 6/6
Put it back into the equation:
6/6 + (-4/6) - (27/6)
Then, take it out of the parenthesis:
6/6 - 4/6 - 27/6
Simplify:
= - 25/6
which is the answer.
Hope that helped !! Have a great day now

Answer:
38.667°
Step-by-step explanation:
the total sum of 3 angles in a triangle is 180
in triangle PQR this means:
P+Q+R = 180
so:
64+x+2x=180
64+3x=180
3x=116
x=116/3=38.667
So Q=X=38.667
