Answer:
x = 10
Step-by-step explanation:
61 - 21 = 40
40 / 4 = 10
x = 10
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
Answer:
∆AKM is a right triangle for it is inscribed in semicircle O.
AM = diameter of semi-circle O = 2R = 2(2) = 4
%22AK%22%2F%22AM%22=cos%2833%5Eo%29
AK+=+AM%2Acos%2833%5Eo%29
AK+=+4cos%2833%5Eo%29
%22KM%22%2F%22AM%22=sin%2833%5Eo%29
KM+=+AM%2Asin%2833%5Eo%29
KM+=+4sin%2833%5Eo%29
The perimeter of a triangle is the sum of the three sides.
perimeter=AK%2BKM%2BAM
perimeter=4cos%2833%5Eo%29%2B4sin%2833%5Eo%29%2B4

Answer: 
Step-by-step explanation:
1. By definition, scientific notation has the following form:
Where:
<em> a</em> is a number between 1 and 10 but does not include 10.
<em> b </em>an integer.
2. When you multiply 3.25 by 7.8 the result is 25.35 and when you multiply 
by 
, you obtain 
, but to write ree thsult in scientific notation, the decimal point must be after the first digit. Therefore, you must move the decimal point one place to the left. So, the exponent changes from 9 to 10:
Answer:
$2,184
Step-by-step explanation:
$6,500 x 2.8% = annual interest
6,500 x 2.8% = $182 annual interest
$182 x 12 years = interest earned in 12 years.
182 x 12 = $2,184
