4a.
So one property of a rhombus is that all sides are congruent to each other. Using this information, we just need to divide the perimeter by 4, in which the quotient is 6. In short, the measure of FI is 6 units.
4b.
Another property of a rhombus is that opposite angles are congruent and that their diagonals bisect the angles. Since we see ∠HIJ is 72°, just multiply it by 2 to get the measure of ∠FGH. The measure of ∠FGH is 144°.
Answer:
Sin O =
Cos O =
Cot O =
Csc O =
Sec O =
Step-by-step explanation:
Do you know the definitions of all the trig functions? If not, you need to memorize them. Also, you need to memorize which functions are positive in each quadrant. All functions are positive in quad I, sine and reciprocal are positive in quad II, tan and reciprocal are positive in quad III, and cos and reciprocal are positive in quad IV. OK?
Tan of an angle is opposite side/adjacent side of a right triangle
If the tan O = - 2. let the opp. side = 2 and adjacent side = 1. Then the hypotenuse =
Sine is positve and equals opp/hyp =
Cos is negative and equals adj/hyp =
Cot is negative and is the reciprocal of the tan or adj/opp =
Csc is positive and is the reciprocal of the sine or hyp/opp =
Sec is negative and is the reciprocal of the cos or hyp/adj =
Answer:
B: T = ½R
Step-by-step explanation:
From the given graph, we see the following;
When T = 2, R = 4
When T = 3, R = 6
When T = 4, R = 8
When T = 5, R = 10
Looking at those values, we can see a pattern where R is always equal to 2T.
Or T = ½R
Thus, option B is the answer.
A percent is just that number over hundred, so if it was 20%, it would be 20/100. That could be termed to differentiate the quantity amounts
Answer:
1/2
Step-by-step explanation:
the slope of a perpendicular line will always be the opposite reciprocal.
