PLEASE HELP ASAP JUST CLASSIFY THE TRIANGLE NOTHING ELSE

Answer 1

Given:

The figure of a triangle.

To find:

The category of the triangle.

Solution:

In the given triangle two angles are equal and their measure is 78 degrees. So, the measure of third angle is

[tex]78^\circ+78^\circ+a=180^\circ[/tex]             (Angle sum property)

[tex]a=180^\circ-78^\circ-78^\circ[/tex]

[tex]a=24^\circ[/tex]

In the given triangle only two angles are equal in means their opposite sides are also equal.

We know that base angles of an isosceles triangle are equal. So, the triangle is isosceles.

All angles are less than 90 degree. So, the triangle is acute.

Therefore, the given triangle is an isosceles acute triangle and the correct option is B.

Triangle E F G is shown. Angle G F E is a right angle. The length of G F is 3 and the length of E F is 4.6. Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.6 Over 3 EndFraction) m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction) m∠E = tan–1(StartFraction 4.6 Over 3 EndFraction)

Answers

Answer:

m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)

Step-by-step explanation:

Given the following

m<GFE = 90 degrees

GF = 3

EF = 4.6

The side opposite to m<E is GF

Adjacent side is EF

Using the SOH CAH TOA identity

tan theta = opp/adj

tan m<E =GF/EF

Substitute the given values

tan m<E  = 3/4.6

m<E = tan^-1 (3/4.6)

Hence the required result is m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction)

Helene invested a total of $1,000 in two simple-interest bank accounts. One account paid 8% annual interest; the other paid 9% annual interest. The total amount of interest she earned after one year was $86. Enter and solve a system of equations to find the amount invested in each account. Enter the interest rates in order as given in the problem. (Hint: Change the interest rates into decimals first.)
at 9%.

Answers

Answer: -600 and 1600 were invested into the two accounts.

Step-by-step explanation:

x = amount invested in the first account.

y = amount invested in the second account.

You start off with this equation

[tex]x + y = 1000[/tex]

[tex]0.08x + 0.09y=86[/tex]

Subtract both sides by y.

[tex]x=1000-y[/tex]

Subsitude 1000 - x for x for the second equation.

[tex]0.08(1000-y)+0.09y=$86[/tex]

Use the distributive property to solve for y.

[tex]80-0.08y+0.09y=86[/tex]

[tex]80-0.01y=86[/tex]

[tex]6=-0.01y[/tex]

[tex]=-600[/tex]

Subsitude -600 for y in the first equation and solve for x.

[tex]x-600=1000[/tex]

[tex]x=1600[/tex]

-600 and 1600 were invested into the two accounts.

A roll of tape has a circumference of 14.8 centimeters. The circumference decreases 2.4 centimeters after you use some of the tape. What is the diameter of the roll after you use the tape? ROUND to the nearest HUNDREDTH. I need answers quick

Answers

Answer:

7.900 cm

Step-by-step explanation:

The computation of the diameter after using the tape is given below:

Since the circumference is 14.8 cm

And it would be decrease by 2.4 cm

So, the new circumference is

= 14.8 - 2.4

= 12.4 cm

Now the radius is

= 12.4 ÷ π

= 3.95

And, the diameter is

= 3.95 × 2

= 7.900 cm

Solve for b. 5b + 8 - 2b = 7b. A 2 B.4/5 C.4/7 D.1/2​

Answers

Answer:

b=2

Step-by-step explanation:

5b + 8 - 2b = 7b

Combine like terms

3b+8 = 7b

Subtract 3b from each side

3b+8-3b = 7b-3b

8 = 4b

Divide each side by 4

8/4 = 4b/4

2 =b

Answer:

b=2

Step-by-step explanation:

Simplifying

5b + 8 + -2b = 7b

Reorder the terms:

8 + 5b + -2b = 7b

Combine like terms: 5b + -2b = 3b

8 + 3b = 7b

Solving

8 + 3b = 7b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-7b' to each side of the equation.

8 + 3b + -7b = 7b + -7b

Combine like terms: 3b + -7b = -4b

8 + -4b = 7b + -7b

Combine like terms: 7b + -7b = 0

8 + -4b = 0

Add '-8' to each side of the equation.

8 + -8 + -4b = 0 + -8

Combine like terms: 8 + -8 = 0

0 + -4b = 0 + -8

-4b = 0 + -8

Combine like terms: 0 + -8 = -8

-4b = -8

Divide each side by '-4'.

b = 2

Simplifying

b = 2
