What is the measure of a base angle of an isosceles triangle if the measure of the vertex tangle is 38 degrees and the two congr
Anit [1.1K]

The measures of the angles of the isosceles triangle are 55, 55 and 70.

Explanation:

An isosceles triangle has two congruent base angles and a vertex angle.

Let b =the measure of one of the base angles.

Let v = the measure of the the vertex angle.

The vertex angle is 40 degrees less than the sum of the base angles.

v = b + b − 40 = 2 b − 40

The sum of the measures of the angles of a triangle is 180.

b + b + v = 180

Substitute 2 b − 40 for v .

b + b + 2 b − 40 = 180

4 b − 40 = 180

+40+40

Combine like terms.

Add 40 to both sides.

4b=220

Divide by 4

4 b/4 = 220 /4

b = 55

v = 2 b − 40

v = 2 ( 55 ) − 40 = 70

What is the value of cosθ given that (−2, −3) is a point on the terminal side of θ ?
snow_tiger [21]

Answer:

-0.555

Step-by-step explanation:

The terminal point of the vector in this problem is

(-2,-3)

So, it is in the 3rd quadrant.

We want to find the angle \theta that gives the direction of this vector.

We can write the components of the vector along the x- and y- direction as:

v_x = -2\\v_y = -3

The tangent of the angle will be equal to the ratio between the y-component and the x-component, so:

tan \theta = \frac{v_y}{v_x}=\frac{-3}{-2}=1.5\\\theta=tan^{-1}(1.5)=56.3^{\circ}

However, since we are in the 3rd quadrant, the actual angle is:

\theta=180^{\circ} + 56.3^{\circ} = 236.3^{\circ}

So now we can find the cosine of the angle, which will be negative:

cos \theta = cos(236.3^{\circ})=-0.555
