Answer:
A = 3244
B = 864
C = 3080
Step-by-step explanation:
700 + a = 3944
-700 -700
a = 3244
3944 - b = c - 80 = 3000
c - 80 = 3000
+80 +80
c = 3080
3944 - b = c ---> 3944 - b = 3080
-3944 -3944
-b = -864 --->
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
It matters what D is.
the way to do it is like 8 to the third power th math is:
8 times 8=64
8 times 64=512
8 times 512=4096
3 times
Answer:
D = 90°
Step-by-step explanation:
the square on the angle means its a right angle and right angle is always 90°
