Please I need your help!! Find the value of x.
A. 15°
B. 17°
C. 21°
D. 35°
E. 142°

Answers

Answer:

x = 21°

Step-by-step explanation:

Triangle = 180°

Angle YXZ = 34°

Angle XZY = (x + 104)°

Angle x = ?

34° + x° + 104° + x° = 180°

138° + 2x° = 180°

2x° = 180° - 138°

2x/2 = 42/2

x = 21°

Is (-3,4) a solution to the equation y=3x+107
O A solution
O Not a solution

Answers

Answer:

no

Step-by-step explanation:

its is not a solution, however if the equal sign actually looks like

[tex] \leqslant [/tex]

then it would be yes

Answer:

Not a solution

Step-by-step explanation:

( x, y ) = ( - 3, 4 )

x = - 3

y = 4

Substitute the values of x and y in the equation,

y = 3x + 107

4 = 3 ( - 4 ) + 107

4 = - 12 + 107

4 = 107 - 12

4 ≠ 95

Therefore,

( - 3, 4 ) is not a solution to the

equation y = 3x + 107.

john wants to measure the hieght of a tree. he walks exactly 100 ft from the base of the tree and looks up. the angle from the ground to the top of the tree is 33. how tall is the tree​

Answers

Answer:

The tree is 64.9 ft tall.

Step-by-step explanation:

Think of a right triangle. Draw the right triangle. The tree is a vertical side of the triangle, so it is a leg with unknown length, so call its length y. The ground, is a horizontal leg with length 100 ft. The angle from endpoint of the horizontal leg on the ground away from the tree to the top of the tree is 33º.

For the 33º angle, y is the opposite leg, and 100 ft is the adjacent leg.

The trig ratio that relates the lengths of the opposite leg to the adjacent leg is the tangent.

tan A = opp/adj

tan 33º = y/100

y = 100 * tan 33º

y = 64.9

Answer: The tree is 64.9 ft tall.

Find the unknown angle measures

Answers

Answer:

Step-by-step explanation:

ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.

so y is the same as 110

and 180 - 110 is 70, so x and z are equal to 70.

i hope this helped you :)

Answer:

y=110, x and z=70

Step-by-step explanation:

110 and y are congruent angles, so they both are 110 degrees.

both angles on the same side of the line always total 180 degrees,

so x and z must be 70.
