So, the ones that are on the inside of the shapes are angles, and the lines are sides. What you’ll do is, you’ll read them as: side angle side(SAS) or, side side side(SSS). So for example problem 3 would be side angle side(SAS), because there is one angle in the middle and two sides on the out side. If you read one as angle angle side(AAS) or side side angle(SSA) or angle side angle(ASA) you’ll put not congruent. I hope this helps.
Answer:
1/2
Step-by-step explanation:
When two lines are parallel, the slopes are the same. In an equation y=mx+b, "m" is the slope which in this case is 1/2. If the lines are perpendicular, the slopes would multiply to -1. So... if they were asking for perpendicular, the answer would be -2.
Answer:
C
Step-by-step explanation:
If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:
(true for <em>y</em> between -π/2 and π/2)
Now take the derivative of both sides and solve for it:
Answer:
The angle θ = 312°.
Step-by-step explanation:
0° < θ < 360°
If cos θ = 2/3 and tan θ < 0
As cos θ is positive and tan θ is negative so the angle is in fourth quadrant.
cos θ = 2/3
θ = 312°
