An isosceles triangle has base angles that each measure 42 degrees.Which equation can be used to find z, the measure of the thir

d angle of this isosceles triangle in degrees
Mathematics

Answer:

z+42+42=180

Step-by-step explanation:

Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to  180. So use this equation:

z+42+42=180

If you need to find z, it is 96.

Check: 96+42+42=180

Last weekend sanjay watched 3 television shows that were each 30 mins long he also watched one movie on television that was 90 m
vodka [1.7K]

Answer:

Sanjay watched television last weekend for 180 minutes.

Step-by-step explanation:

Sanjay watched 3 television shows and one movie on television last week.

Time duration of 1 television shows = 30 mins

Time duration of 3 television shows = 3* 30 = 90 mins

Time duration of movie = 90 mins

Total number of minutes Sanjay watched television last weekend = Time duration of 3 television shows + Time duration of movie

= 90 + 90

= 180 min

So, Sanjay watched television last weekend for 180 minutes.

X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Roun
lawyer [7]

Answer: Area = 28.2m²

Step-by-step explanation: The triangle YXZ is shown in the figure below.

Area of a triangle is calculated by the formula:

A=\frac{1}{2} (base*height)

According to the figure, the base of this triangle is b = 8.3m.

Height is a perpendicular line created from one side and intersecting the opposite angle.

To determine the height, use trigonometric relations to angle 68:

sin(68)=\frac{h}{7.3}

h = 7.3*sin(68)

h = 7.3*0.93

h = 6.8

Now, area of triangle YXZ is

A=\frac{1}{2} (8.3*6.8)

A = 28.2

Area of triangle YXZ is 28.2m².

What are the different measurements for angles and how do we convert between them? Explain with examples of your own.
artcher [175]

Angles are usually  given in degrees or in radians.

A circle is 360 degrees.

To convert degrees to radians, multiply the known degree by π/180.

Example 45 degrees = 45 x π/180 = 0.7854 radians.

To convert radians to degrees, multiply the known radian by 180/π.

5 radian = 5 x 180/π = 286.48 degrees.

(3,4) and (-5,6) are "coordinate planes".

These appear in algebra and math when you're graphing. These coordinate planes consist of "x" and "y" (x,y). The x's (which are 3 and -5 in your situation) should be graphed accordingly using the x-axis and the y's (which are 4 and 6 in your situation) should be graph accordingly using the y-axis.
