17. Classify Each Angle Pair then find the value of X

IRISSAK [1]

Given -

If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

To find -

m∠2.

Concept -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

Solution -

$\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}$

$\rightarrow\sf{13x+5x+24-6=180}$

$\rightarrow\sf{18x+18=180}$

$\rightarrow\sf{18(x+1)=180}$

$\rightarrow\sf{x+1=\frac{180}{18}}$

$\rightarrow\sf{x+1=10}$

$\rightarrow\sf{x=10-1}$

$\rightarrow\boxed{\bf{x=9}}$

m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°

Henceforth, m∠2 = 39°

Let the given rhombus be abcd in which ab = bc = cd = da = 20 cm and

natka813 [3]

Answer:

384 cm²

Step-by-step explanation:

Property of rhombus :

Diagonals of rhombus bisect each other and are perpendicular to each other

Given :

Rhombus ABCD and its diagonals AC and BD bisect each other at O
AC ⊥ BD
AB = BC = CD = DA = 20 cm
AC = 24 cm

Solving :

Area of the given rhombus is twice the Area of ΔABC formed by the given diagonal and two adjacent sides.

2 × 1/2 × OB × AC
24 × OB
24 × √AB² - AO²
24 × √20² - (AC/2)²
24 × √400 - 144
24 × √256
24 × 16
384 cm²

Our math team had m students last year, but this year it has already n students! By what percent did the number of students grow

AlekseyPX

For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
$(n / m) * 100 - 100$
Answer:
the number of students did grow by:
$(n / m) * 100 - 100$
