Answers

Answer:

45

Step-by-step explanation:

Well, it is not 90 degrees, as it is not a right angle.

It cannot be 180 degrees as that would be a straight line and a triangle's whole angle measure is 180 degrees.

It is an acute angle, and appears to be half of 90 degrees, so I would have to say 45 degrees.

Not enough information is false because you can infer that it is 45 degrees by looking at it.

Hope that helps!

The answer is 45 because the person on top put 45

Which best explains whether or not all isosceles triangles are similar?

All isosceles triangles are similar. Two angles within each triangle are always congruent.
All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180°. Therefore, the third angle can always be determined.
All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.

Answers

Answer:

C: All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.

Step-by-step explanation:

An Isosceles triangle is one that 2 of it's sides are equal and thus two of its angles are congruent which means they are equal.

Now, another Isosceles triangle may not necessarily be similar to another one because the congruent angles in one Isosceles triangle may not be the same with that of another Isosceles triangle.

Thus, correct answer is option C

Steve invests $1,800 in an account that earns 3.7% annual interest, compounded continuously. What is the value of the account after 10 years? Round your answer to the nearest dollar. A. about $2,466 B. about $2,589 C. about $2,601 D. about $2,606

Answers

Answer:

B. about $2,589

Step-by-step explanation:

Given data

P=$1,800

R= 3.7%

T=10years

The expression for the compound interest is given as

A= P(1+r)^t

substitute

A= 1800(1+0.037)^10

A= 1800(1.037)^10

A=1800*1.43809495884

A=$2588.570

Hence the answer is  B. about $2,589

12.5×8 is 100

1/8 ×8 is 8/8

A mountain climber ascends a mountain to its peak. The peak is 14,090 ft above sea level. The climber then descends 490 ft to meet a fellow climber. Find the climber’s elevation above sea level after meeting the other climber.


13,600 ft

14,580 ft

–13,600 ft

9,190 ft

Answers

Answer:

13,600 feet above sea level

Step-by-step explanation:

The climber was at 14,090 feet above sea level, and then they went 490 feet closer to sea level to meet the other climber. Since they’re moving closer to sea level and you want to know how far *above* sea level they are, subtract 490 from 14,090. 14,090-490=13,600 feet above sea level

If 5x + 4y= 13 and 4x + 5y = 14, find the value of (x - y).​

Answers

Answer:

x - y = - 1

Step-by-step explanation:

Given the 2 equations

5x + 4y = 13 → (1)

4x + 5y = 14 → (2)

Subtract (2) from (1) term by term , that is

(5x - 4x) + (4y - 5y) = 13 - 14

x - y = - 1

Answer:

x = 1

y = 2

x - y = -1

Step-by-step explanation:

5x + 4y= 13,   then 4y = 13 - 5x, then y = (13 - 5x)/4

4x + 5y = 14

substitute for y:

4x + 5(13 - 5x)/4 = 14

simplifying:

4x + (65 - 25x)/4 = 14

4x + 16.25 -6.25x = 14

-2.25x = -2.25

x = 1

y = (13 - 5)/4 = 2
