Answer:
Step-by-step explanation:
- 4x + 1.3 = -7.9
- 4x = -7.9 - 1.3
- 4x = -9.2
- x = -9.2/4
- x = - 2.3
See the picture with letters attached to better understand the problem
we know that
in the right triangle ABC
AB=BC----------> by angle 45°
AC²=AB²+BC²-----> AC²=(√2)²+(√2)²----> AC²=4-----> AC=2
in the right triangle ACD
tan 60°=y/AC--------> y=AC*tan 60°-----> y=4*tan 60°----> y=4√3
the answer isy=4√3
Spacing needs to be more clear instead of having a giant paragraph. you do not write math in giant paragraphs do you
