Ill give brainliest <br> Triangle Sum Theorem CLASSWORK
zepelin [54]

Step-by-step explanation:

Sum of angles in a triangle = 180°.

Question 3:

We have 90° + 61° + (14x + 1)° = 180°.

=> 14x° + 152° = 180°

=> 14x° = 28°

=> x = 2.

Question 4:

We have 70° + 55° + (4x + 3)° = 180°.

=> 4x° + 128° = 180°

=> 4x° = 52°

=> x = 13.

Step-by-step explanation:

Eva invests $6400 in a new savings account which earns 3.4% annual interest, compounded continuously.

We have to find the value of her investment after 6 years,

Now, using the formula for the compound interest we can get the value of her investment.

So, it will be V = 6400 (1 + \frac{3.4}{100} )^{6} = 7821.74 Dollars (Approximate)

Maria looked at the architectural plan of a room with four walls in which the walls meet each other at right angles. The length
babymother [125]
Using the Pythagorean theorm, 
a^2 + b^2 = C^2, where a nd b are the side lengths and c is the hypotenuse ( diagonal line)

If it was a square both sides would be the same length so we would have:
13^2 +13^2 = c^2
169 + 169 = c^2
338 = c^2

c = SQRT(338) = 18.38

18.38 is larger than the 15.26 given in the problem , so the room is not a square.
