The answer is 60 because a right triangle has 90 degrees
So 90-30 (the given angle) is 60 because 60+30 gives the required 90 degrees.

You need to use foil here (first, outer, inner, last).
gxg=g^2
gx2=2g
7xg=7g
7x2=14
g^2-2g-7g+14   then simplify   g^2-9g+14   is the answer

Х<br> 30°<br> Calculate the size of angle x.<br> angle x =<br> I
Furkat [3]

If one Angle is = 30

And the other two angles are equal

Given: x = l

ATQ

⇒30+x+l= 180

⇒x + x = 180-30

⇒2x = 150

⇒x = 150/2

⇒x = 75

Therefore x = 75

And the angles are 30, 75 and 75

Trigonometry<br> Trigonometric Functions <br> Given: Cos θ = (3/5), Find: Csc θ
torisob [31]

The value of \csc \theta is \frac{5}{4}

Explanation:

Given that the function cos \ \theta is cos \ \theta= \frac{3}{5}

We need to determine the value of \csc \theta

<u>The value of Opposite side of the triangle:</u>

The formula for cos \ \theta is given by

cos \ \theta= \frac{adj}{hyp}=\frac{3}{5}

The value of opposite side can be determined using the formula,

opp=\sqrt{hyp^2-adj^2

opp=\sqrt{5^2-3^2}

opp=\sqrt{25-9}

opp=\sqrt{16}=4

Thus, the value of opposite side is 4

<u>The value of </u>sin \ \theta<u>:</u>

The formula for sin \ \theta is given by

sin \ \theta= \frac{opp}{hyp}

Substituting the values, we have,

sin \ \theta= \frac{4}{5}

Thus, the value of sin \ \theta is \frac{4}{5}

<u>The value of </u>\csc \theta<u>:</u>

The formula for \csc \theta is given by

csc \ \theta=\frac{1}{sin \ \theta}

Substituting the values, we have,

csc \ \theta=\frac{1}{\frac{4}{5}}

csc\ \theta= \frac{5}{4}

Thus, the value of \csc \theta is \frac{5}{4}

Hence, the value of \csc \theta is \frac{5}{4}

Select the mathematical terms that mean "opposite of". A. reciprocal. B. negative. C. additive inverse. D. multiplicative E. inv
Margaret [11]
The mathematical term "opposite of" means B. negative. An example can be perceived in a Cartesian coordinate system in which the opposite of -3 is +3 or of -1 is +1. Opposite means the opposite sign of a specific number.
