This triangle is obtuse( as it's one angle is greater than 90°) as well as isosceles (as it's two sides are equal).

Answer:

Step-by-step explanation:

From the given figure, two sides of the given triangle are equal, which makes the triangle an isosceles triangle as an isosceles triangle has two sides equal.

Also, the angle given in the figure is greater than 90° that is 104°, therefore the angle is obtuse angle.

Since, the scalene triangle is that triangle in which all the sides are not equal, but here two sides are equal, therefore it is not a scalene triangle.

This is also not an equilateral triangle as all the sides are not equal.

The angle given is obtuse in nature and not right angle or acute.

Thus, the given triangle is isosceles triangle and has obtuse angle.

Therefore, option C and E is correct.

Which of the following is a solution to 2sin^(2)x+sinx-1=0

lukranit [14]

Hello,

$2*sin^2(x)+sin(x)-1=0\\\Delta=1+4*2*1=9=3^2\\sin^2(x)=\frac{-1-3}{4} =-1\ (impossible)\\or\\sin^2(x)=\frac{-1+3}{4} =\dfrac{1}{2}\\sin(x)=\dfrac{\sqrt{2} }{2} \Longrightarrow (x=45^o\ or\ x=135^o)\\or\\sin(x)=-\dfrac{\sqrt{2} }{2} \Longrightarrow (x=315^o\ or\ x=225^o)\\$

Answer A : 45°

Laticia randomly selected 25% of the seventh-grade students in her school and asked them their favorite season. Of the students

Vlad [161]

Answer:

D. 200

Step-by-step explanation:

Laticia doing her survey on a sample that has a size of about 25% of the population. That means the sample is approximately four times larger than the sample she takes. Unless its ratio or percentage, any data she takes will be 1/4 of the population. If 51 student of her sample choose summer as their favorite, predicted number on the population will be:

51 * (100%/25%)=

51 * 4= 204

The number will be around 200.
