Answer:
B.99°
Step-by-step explanation:
105°+ 66°+90°+ angle c=360°
angle c= 360° - 261
=99°
By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.
Thus,


is a constant which can be found using a calculator:
with calc in pc: view → scientific → 27→sin = 0.45399,
thus x=34/0.45399=74.89
Answer: 74.89
Answer:
8 = 16
Step-by-step explanation:
1/4 = 4
/8
Cross multiply:
1 * 8 = 4 * 4
Simplifying
1 * 8 = 4 * 4
Multiply 1 * 8
8 = 4 * 4
Multiply 4 * 4
8 = 16
Solving
8 = 16
Answer:
v=14, u=14
Step-by-step explanation:
The 45-45-90 theorem states that the hypotenuse is
times the bases of the triangle. So, to find one of the bases, we need to divide
. Thus,
.
h = 2t - d
multiply both sides by 2 to eliminate the fraction
2t = d + h
subtract d from both sides
2t - d = h ⇒ h = 2t - d
