Answer:

No. It can be obtuse angle are angles greater than 90° but less than 180°

And for an isosceles triangle, two angles must be equal so if two angles are greater than 90° that mean the sum of angle in a triangle is above 180° which is not possible

Find the value of x please

Evgesh-ka [11]

Answer:

x = 170/34 = 5

Step-by-step explanation:

The sum of angle 1 and angle 2 is 180 degrees. They form a straight line.

So, just add the two equations together, set them equal to 180 and solve for x.

12x+19 + 22x - 9 = 180

34x + 10 = 180

34x = 180 - 10 = 170

x = 170/34 = 10/2 = 5

What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent

Pani-rosa [81]

Answer:

$19.625\text{ cm}^2$

Step-by-step explanation:

GIVEN: A square with base $5\text{ cm}$ , a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be $x\text{ cm}$

radius of circle $=\frac{\text{length of base of square}}{2}$

$x=\frac{5}{2}\text{ cm}$

$x=2.5\text{ cm}$

Area of circle $=\pi(radius)^2$

$=3.14\times(2.5)^2$

$=19.625\text{ cm}^2$

Hence the area of circle that perfectly fits inside the square is $19.625\text{ cm}^2$
