The angles of a triangle always equal to 180 degrees.

Knowing this, you can solve this by this equation

Angle A + Angle B + Angle C = 180

43 + 85 + Angle C = 180

Angle C = 180 - 43 - 85
Angle C = 52

123.51 divided by 2.3 show your work
Darya [45]

Answer:

53.7

Step-by-step explanation:

So first move the decimal in 2.3 by one to the left, making it 23. Now what you do to one thing you do to the other, now 123.51 becomes 1235.1. Now you have 1235.1 / 23. 23 goes into 1235; 53 times, leaving you with 16.1. Now we take 16.1 / 23. When you do that you get .7. Therefore your answer is 53.7

Hopefully this helped!

Given that k-5, k+7, k+55 are three consecutive terms in a geometric sequence, solve for k​
choli [55]

Answer:

k = 9

Step-by-step explanation:

Given:

Consecutive Terms:  k-5, k+7, k+55

Required:

Determine the value of k

To do this, we make use of the concept of common ratio.

The common ratio (r) of a geometric sequence is:

r = \frac{T_{n}}{T_{n-1}}

In other words:

r = \frac{T_3}{T_2} = \frac{T_2}{T_1}

Where 1, 2 and 3 represents the terms of the progression/sequence

So:

r = \frac{T_3}{T_2} = \frac{T_2}{T_1} becomes

\frac{k+55}{k+7} = \frac{k+7}{k-5}

Cross Multiply:

(k+55)(k-5) = (k+7)(k+7)

Open Brackets

k^2 + 55k - 5k - 275 = k^2 + 7k + 7k + 49

k^2 + 50k- 275 = k^2 + 14k + 49

Collect Like Terms

k^2 - k^2 + 50k-14k  = 275 + 49

36k  = 324

Solve for k

k = 324/36

k = 9
