Find the value of x.

Jet001 [13]

Answer:

x=18 degrees

Step-by-step explanation:

since this is a triangle, you know that the three angles added up equal 180 degrees. since it is a right triangle, 25+3x+11=90 (the right angle=90). then you just solve for x: 3x=54, x=18

I need some help with this

Ivenika [448]

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

$sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}$

AKA SohCahToa.

To find the height, we will use sine.

$sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14$

To find the length we will use cosine.

$cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6$

Ssignment

AnnZ [28]

Part a: The value of x is 33°

Part b: The measure of each base angle is 69°

Explanation:

It is given that the vertex angle of an isosceles triangle measures 42°.

The base angle in the triangle has a measure of $(2x+3)^{\circ}$

Part a: To determine the value of x

Since, in an isosceles triangle the base angles are always equal.

Thus, the three angles in an isosceles triangle add up to 180°

Hence, we have,

$42+2x+3+2x+3=180$

$42+4x+6=180$

$4x+48=180$

$4x=132$

$x=33^{\circ}$

Thus, the value of x is 33°

Part b: To find the measure of each base angle.

Base angle = $(2 x+3)^{\circ}$

Substituting $x=33^{\circ}$ , we get,

$Base \ angle = (2(33)+3)^{\circ}$

$=(66+3)^{\circ}$

$=69^{\circ}$

Thus, the measure of each base angle is 69°
