1. parallelogram, quadrilateral, rectangle, square
2. A
Step-by-step explanation:
1. Not a rhombus/trapezoid
2. None of the other choices make sense
Answer:
2.3
Step-by-step explanation:
Using SOH CAH TOA, we can label CB as the alternate side seeing as it's opposite to the known angle 50 degrees. We know AB is the hypotenuse since it's the longest side. Therefore CA must be the alternate side.
Since we want to know BC, and we know information about AB, we need to use the use of the hypotenuse and the opposite. In SOH CAH TOA, SOH uses both of these.
Using S O H, we understand that sin(50) * 3 = CB
Therefore CB = 2.3 to 1 decimal place.
Answer:
x = 1.7272727272
Step-by-step explanation:
The expression for perimeter of triangle is 6x + 21
<em><u>Solution:</u></em>
Given that,
Let the length of the bottom of the triangle be "x"
Another side is 7 more than 4 times the length of the bottom of the triangle
Length of another side = 7 + 4x
The last side is 14 more than the bottom of the triangle
Length of last side = 14 + x
<em><u>The perimeter of triangle is given as:</u></em>
Perimeter = sum length of length of all 3 sides of triangle
Thus expression for perimeter of triangle is 6x + 21
Answer:
B
Step-by-step explanation:
it goes from the 7th power to the 4th power. So add them together and you get 11
