Hello There!

The triangle shown in the image would be an acute triangle

An acute triangle is a triangle where all three sides are less than 90°

In the image, none of the angles shown are greater than 90° so this

is an example of an acute triangle

Answer:

Acute

Step-by-step explanation:

Note the definitions:

Obtuse: At least one of the angles are greater than 90°

Equilateral: All angles are congruent & equal to 60°

Acute: All angles are less than 90°

Right: At least one angle is equal to 90°

In this case, the triangle is a D) acute, for it fits the requirement for being an acute... all angles are less than 90°.

1. A point on the ground is 50 feet from my house. The angle of elevation to the top of the house is 48 Find the height of the h

Georgia [21]

Answer:

(1)55.5 feet

(2)7.5 feet

Step-by-step explanation:

Question 1

The diagram is attached below.

Using Trigonometric ratio

$\tan 48^\circ = \dfrac{h}{50} \\h=50 \times \tan 48^\circ\\h=55.5$ feet (to the nearest tenth)$

The height of the house is 55.5 feet to the nearest tenth.

Question 2

In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.

Using Trigonometric ratio

$\tan 15^\circ = \dfrac{2}{x} \\x \tan 15^\circ=2\\x=2 \div \tan 15^\circ\\x=7.5 $ feet (to the nearest tenth)$

The distance the bird must fly to be directly above the fish is 7.5 feet.

Which of the following expressions is a polynomial?

Assoli18 [71]

Hello from MrBillDoesMath!

Answer:

The second choice

Discussion:

The first choice is not a polynomial because it contains sqrt(x)

The third choice is not a polynomial because it contains (1/x)

The fourth choice is not a polynomial because it contains x in the exponent (ie. 5^x)

Thank you,

MrB

7 Given: -8(w + 1) = -5(w + 10); Prove: w = 14 Statements

LenKa [72]

Answer:

w=14

Step-by-step explanation:

-8(w + 1) = -5(w + 10)

Remove the parentheses

-8w-8+-5w-50

Move terms

-8w+5w=-50+8

Collect like terms and calculate

-3w=-42

Then divide on both sides
