Answer:
<em>(16.2t+3.4u+2.9)cm</em>
Step-by-step explanation:
A triangle is a plane shape that has three sides. <em>The perimeter of a triangle is gotten by taking the sum of all the lengths of the three sides</em>. Let the length of the three sides by s1, s2 and s3, the perimeter of the triangle will be expressed as;
P = s1+s2+s3
Given the side lengths
s1 = (8.1t-6.1)cm
s2 = (8.1t+7.1)cm
s3 = (3.4u+1.9)cm
Perimeter of the triangle = 8.1t-6.1+8.1t+7.1+3.4u+1.9
collect the like terms
P = 8.1t+8.1t+3.4u-6.1+7.1+1.9
P = 16.2t+3.4u+2.9
<em>Hence the expression that represents the perimeter, in centimeters, of the triangle is (16.2t+3.4u+2.9)cm</em>
Since the two shapes above are congruent, meaning they are the same, you can observe that three of the four angles for the total shape are given. The angles that were given include 133, 86, and 41 degrees. However, a quadrilateral has 360 degrees, and you can find the missing angle by adding up the three given degrees and subtracting it from 360. 133+86+41=260 degrees. You can then subtract it from 360. 360-260=100. So, the degrees of the missing angle is 100 degrees.
Answer:
OC
Step-by-step explanation:
The x value is the same on both side of the equation but the other number are not (8≠-5) so the equation can't be true no matter the value plugged for x
The equation is 10 + 2x= 56; 56 - 10= 46; 46 ÷ 2= 23,
The answer is 23 people.
Hope this helps :)
