Answer: 60cm
Step-by-step explanation:
6 times 2 is 12
12 times 5 is 60
Answer:
x = -4/9
Step-by-step explanation:
X + B = C
x + (-8/4) = (22/-9)
x = (8/4) - (22/9)
x = 2 - 22/9 = 18/9 - 22/9 = -4/9
The rest of the question is the attached figure
========================================
solution:
========
As show in the attached figure
∠M = ∠R = 54.4°
∠N = ∠T = 71.2°
∠O = 180° - (∠M + ∠N) = 180° - (54.4°+71.2°) = 54.4°
∠S = 180° - (∠R + ∠T) = 180° - (54.4°+71.2°) = 54.4°
∠O = ∠S = 36°
∴ Δ MNO is similar to Δ RTS
So, the correct statement:
The triangles each have two given angle measures and one unknown angle measure.
First lets see the pythagorean identities

So if we have to solve for sin theta , first we move cos theta to left side and then take square root to both sides, that is

Now we need to check the sign of sin theta
First we have to remember the sign of sin, cos , tan in the quadrants. In first quadrant , all are positive. In second quadrant, only sin and cosine are positive. In third quadrant , only tan and cot are positive and in the last quadrant , only cos and sec are positive.
So if theta is in second quadrant, then we have to positive sign but if theta is in third or fourth quadrant, then we have to use negative sign .
Because each ticket costs 1 and she spends 8 she would be buying 8 tickets
She has 8 friends so each one would get 1 ticket
The answer is 1
