Find x

Need gelppppppppppp

Answers

Answer:

The Value of x is 10.

Step-by-step explanation:

Consider ABCD is a Parallelogram where

∠BCA = 43°

∠CBA = 98°

∠ACD = (2x+9)

To Find:

x = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

In ΔABC

$\angle ABC+\angle BCA+\angle CAB=180\n\n98+43+\angle CAB=180\n\therefore m\angle CAB =180-141=39\°$

Now CD || BA .......opposite sides of Parallelogram is parallel

$\angle CAB=\angle ACD$ .........Alternate Angles are equal

Substituting the values we get

$39=2x+19\n2x=20\n\n\therefore x=(20)/(2)=10\n\n\therefore x=10$

The Value of x is 10.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Last year the girls’ basketball team had 8 fifth-grade students and 7 sixth-grade students which is 8/7.

In the ratio form, it is 8 : 7.

Here goes problem 4 i need help

Answers

The only tricky thing about this problem is that you have to know
the formula for the area of a triangle. The formula is

   Area of a triangle = (1/2) times (length of the base) times (the height) .

In this picture, 'x' is the base, and 'h' is the height. That's all you need
in order to find the area. You don't need to know 'y' or 'z' at all.

   Area = (1/2) x (base) x (height)

   = (1/2) x (13) x (6)

   = (1/2) x ( 78 ) = 39 inches²

multiply 13*6=78 then multiply with .5 (78*.5=39)
