Answer:
x ≈ 2.29 cm
Step-by-step explanation:
From the picture below we are given a right angle triangle and asked to find the value of x. We can use the SOHCAHTOA principle to find the side x.
Base on the angle given the adjacent side of the triangle is x while the hypotenuse is given as 4 cm. Let's find the value of x .
cos 55° = adjacent/hypotenuse
cos 55° = x/4
cross multiply
x = 4 cos 55°
x = 4 × 0.57357643635
x = 2.2943057454
x ≈ 2.29 cm
Answer:$466.25
Step-by-step explanation:
9.50(43)+10.50(5.5)
Step-by-step explanation:
Here
5x+16+7x-3+6x+5 = 180(being sum of triangle)
or, 18x=180-18
or, x= 162/18
so, x = 9
now,
here,
<ACD = <ACB(diagonals of parallelogram bisect eachother)
or, <ACD = 7x-3
or, <ACD = 7×9-3
or, <ACD = 63-3
So, <ACD = 60°
Answer:
POLYNOMIAL is a 10-letter word
Step-by-step explanation:
A polynomial is such an expression.
Virtually any kind of algebraic expression is made by adding or subtracting terms, grouping them, applying functions to them, or dividing them. (A term is already a product; increasing the number factors doesn't change that.)
A polynomial is a special kind of sum-of-terms expression involving terms that are non-negative integer powers of a variable.
