The greatest common factor of 49 and 84 is 7
Answer:
56.6m
Step-by-step explanation:
Using SOH = opp/hyp
Where θ = 45°
Hpy = 80m
Opp = ?
Sin θ = opp/hpy
Sin 45 = opp/ 80
Sin 45 × 80 = opp
0.7071 × 80 = opp
Opp = 56.568
~ 56.6m
Hence the height of the top of the tree is 56.6m
The last step is dividing both sides by 4: 4m=98 which would become: m=24.5
Hope this helps :)
25% of 584 is 146. If you meant to say "25% off of the dealer's cost", the answer would be $438, since you're finding what 25% of the original price is (146) and subtracting it from the original price. The equation would be 584 - 146 = 438. I hope this helped <3
Answer:
174 CM²
Step-by-step explanation:
First we split up the triangular prism into shapes we can better understand (2 triangles, and 2 rectangles)
We solve the area of the triangles by using the formula to the area of a triangle (B·H÷2) 8·6÷2=24
There are 2 triangles therefore we get 2*24 which is 48 CM²
Now we calculate the area of the rectangles (7·10=70, 8·7=56)
Finally we add up all the numbers (70+56+48=174 CM²)
Therefore the surface area of the triangular prism is 174 CM², respectively.
