Answer:
56
Step-by-step explanation:
I don't quite understand your question but I assumed you meant what is 70% of 80
30/7 +30/7=60/7
60/7-22/7=38/7
59/7 -38/7=21/7
21/7 -19/7=2/7
Answer:
17.7 cm^2
Step-by-step explanation:
Use trig to find the height of the triangle. Then the area is bh/2.
Extend side BC to the right until it is vertically below point A. Draw a segment from point A vertically down until it intersects the extension of side BC. Call the point of intersection D. <D is a right angle.
Use triangle ABD to find the height, AD, of triangle ABC.
For <B of 37 deg, AD is the opposite leg. AB is the hypotenuse. The trig ratio that relates the opposite lefg to the hypotenuse is the sine.
sin B = opp/hyp
sin 37 deg = AD/13.1
AD = 13.1 * sin 37 deg
AD = 7.9
AD is the height of triangle ABC. BC is the base. We can find the area of triangle ABC.
area = bh/2
area = (4.5 cm)(7.9 cm)/2
area = 17.7 cm^2
Answer:
(3, -2)
Step-by-step explanation:
2+4 = 6
3-7 = -4
6/2 = 3
-4/2 = -2
XLVIII or 48.3. Im not sure if its right and you may want to double check with other answers.
