Which represents an exterior angle of triangle XYZ? O LXZ - 1


Answer 1

An exteriorangle of ΔXYZ is ∠HXJ.

The correct option is D.

What is an angle measure?

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

As per the provided diagram, the exterior angles in the ΔXYZ are:










From the given choices, ∠HXJ is an exterior angle of ΔXYZ.

Graph and find the x-intercept, y-intercept, domain, range, and horizontal asymptote of the function y = 4x


The function y=4x is a line. As such, its domain and range is the whole real number set \mathbb{R}, and it has no horizontal nor vertical asymptotes.

Moreover, there's no constant term, so it's x and y intercept is the origin (0,0).

Y=AB-8. Trying to learn how to solve for A.




Step-by-step explanation:

So we have:


First, add 8 to both sides. The right will cancel:


Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:

Angle of the Sun A 96-ft tree casts a shadow that is 120 ft long. What is the angle of elevation of the sun



The angle of elevation of the sun is 39⁰

Step-by-step explanation:


height of the tree, h = 96 ft

length of the shadow, L = 120 ft


                                                   | 96ft





Completing this triangle to cut across the top of the tree gives you a right angled triangle with θ as the angle of elevation of the sun.

Apply trig-ratio to determine the angle of elevation of the sun;

tanθ = opposite side / adjacent side

tanθ = 96 / 120

tanθ = 0.8

θ = tan⁻¹(0.8)

θ = 38.7⁰

θ = 39⁰

Therefore, the angle of elevation of the sun is 39⁰

Can someone explain how to do it aswell please and thank you



B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*
