The angles are in the ratio of 5:6:9.
Let the angles be represented by:
5x, 6x, and 9x.
The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9
The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.
Answer:
2^3 + 5^2 = 34
7^2 - 3^3 = 22
8^2 + (square root) 100 = 74
Step-by-step explanation:
Hope this helps! Lol I couldn't find the square root symbol.
Answer:
$35.97
Step-by-step explanation:
the regular price is 59.95
40% discount so
let's say the price now is x and i am gonna do fractions
x/59.95 = 40%/100
100 x X = 100x
59.95 x 40 = 2398
i divide 2398 by 100 which equal 23.98
40% is 23.98 and then i do 59.95 - 23.96 = 35.97
DONE!
= 11( - 1)
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a₁ is the first term and r the common ratio
Here a₁ = 11 and r = = = 2 , then
= = 11 ( - 1)

Answer:
Step-by-step explanation:
To find the scale factor from ΔDEF to ΔRST, find a measure on ΔDEF and a corresponding measure on ΔRST, then write them in the form required for the scale factor.
Here, there are numbers on DE, RS, and ST. We see by the similarity statement ΔDEF ~ ΔRST that DE corresponds to RS, so the scale factor is ...
ΔDEF : ΔRST = DE : RS = 3 : 4 . . . scale factor
__
Using that scale factor, you can write a proportion to find the value of x.
3 : 4 = x : 16 ⇒ 3/4 = x/16
Multiplying the fraction equation by 16, we have ...
x = 16(3/4)
x = 12
