Answer:

  c = 108°

  d = 106°

Step-by-step explanation:

There are 2 basic rules involved here. From them, a number of others can be derived in order to simplify some calculations.

  1. angles forming a linear pair are supplementary (total 180°)
  2. interior angles of a triangle total 180°

The derived relations we can use in this problem are ...

  • vertical angles are congruent
  • an exterior angle of a triangle is equal to the sum of the opposite interior angles

__

<h3>c</h3>

The vertical angle to 78° is one of two remote interior angles with respect to exterior angle c. The other is the one marked 30°. That means ...

  c = 78° +30* = 108°

__

<h3>d</h3>

Angles d and 30° are two of the three angles in the largest triangle. The third is the vertical angle to 44°, so it is 44°. The sum of angles in that triangle is 180°:

  d + 30° +44° = 180°

  d = 180° -74° = 106°

In this triangle, what is the value of x? Enter your answer, rounded to the nearest tenth, in the box. x = yd A right triangle w
Eduardwww [97]

Answer: 47.4 yds.

So, if this is a right triangle then you will have a hypotenuse, opposite Leg, and the adjacent. I get it that the first Leg is X an the other is 40 and the hypotenuse is 62.

C=62

A=40

B= X

We gonna use the Pythagorean theorem to solve this problem

C^2=a^2+b^2

62^2=40^2+x^2

x^2 = (62^2) -(40^2)

x^2= 3844-1600

x^2= 2244

x= 47.3708771293

U-5=-8 is tell solution of equation ​
ivanzaharov [21]

Answer:

u = -3

Step-by-step explanation:

Solve for u:

u - 5 = -8

Hint: | Isolate terms with u to the left hand side.

Add 5 to both sides:

u + (5 - 5) = 5 - 8

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

u = 5 - 8

Hint: | Evaluate 5 - 8.

5 - 8 = -3:

Answer: u = -3
