Answer:

D) The measure of <em>x</em><em> </em>is 55 degrees and <em>b</em><em> </em>= 16.38.

Step-by-step explanation:

If the complimentary angle is 35 degrees, then <em>x</em> must be 55 degrees. <em>b</em><em> </em>= 16.38 according to the right triangle ratio which states that <em>b</em> = 4/5(<em>c</em>). Since <em>c</em><em> </em>is 20, <em>b</em><em> </em>is 16.38.

Answer:

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180

x = 180° - (90 + 35)° = 180° - 125° = 55°

----------------------------------------------------------

Since the triangle is right use the cosine ratio to solve for b

cos35° = \frac{adjacent}{hypotenuse} = \frac{b}{20}

Multiply both sides by 20

20 × cos35° = b, hence

b = 16.38 ( to 2 dec. places )

In a right triangle ABC angle B is the right angle and m angle C = 30 degrees if AC = 10 what is AB
Sindrei [870]

Answer:

  • AB = 5

Step-by-step explanation:

This is a 30°-60°-90° right triangle.

AC is hypotenuse, AB is opposite side to 30° angle.

We know that in such a triangle the side opposite to 30° angle is half the hypotenuse.

<u>So we have:</u>

  • AB = 1/2AC = 1/2(10) = 5

Find the midpoint of the line using the midpoint formula.<br> Midpoint of AB:______
dimaraw [331]

Answer: MP=(1,1)

Step-by-step explanation:

MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})

MP= (\frac{-2+4}{2})(\frac{-3+5}{2}) -2+4=2  -3+5=2

MP= (\frac{2}{2})(\frac{2}{2}) 2/2=1

MP= (1,1)

Angle measures and segment lengths. Algebra Find the value of each variable.
dolphi86 [110]

Answer:

x = 60°

Step-by-step explanation:

According to the Outside Angles Theorem, the angle formed by the two tangents in the diagram above is equal to half of the difference of the measures of two arcs  that are intercepted.

Therefore:

x = \frac{1}{2}(360 - 120) - 120)

x = \frac{1}{2}(240 - 120)

x = \frac{1}{2}(120)

x = 60°
