Claire says that she can draw an obtuse equilateral triangle. Is she correct? Explain.

No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.

Hope I Helped (:

No, she is not correct. an obtuse triangle is a triangle with angles equal to more than 90. An equilateral triangle has all triangle measures 60. since 60<90, Clarie is making a false statement

It is true that the product of two consecutive even integers are always one less than the square of their average.

Step-by-step explanation:

Let the two consecutive odd integers be 1 and 3.

The product of 1 and 3 is (1 $\times$ 3)=3
The average of 1 and 3 is (1+3)/2 =4/2 = 2
The square of their average is (2)² = 4

∴ The product 3 is one less than the square of their average 4.

Let the two consecutive even integers be 2 and 4.

The product of 2 and 4 is (2 $\times$ 4)=8
The average of 2 and 4 is (2+4)/2 =6/2 = 3
The square of their average is (3)² = 9

∴ The product 8 is one less than the square of their average 9.

Thus, It is true that the product of two consecutive even integers are always one less than the square of their average.

Answer:

285

Step-by-step explanation:

use algebra

third is x

second is 4x

first is 4x-3

x+4x+4x-3

9x-3 = x+x+1+x+2

9x-3=3x+3

12x=6, divide x=2

third is 2, sec is 8, first is 5

Answer:

64°

Step-by-step explanation:

First, we have to find the angle situated in R, the addition of all angles in a triangle is 180° so that means:

x + 68 + 48 = 180

x = 180-116 = 64°

Now, remember that this angle (64°) is the same as this one = ?, thanks to one property.

So basically, that angle has the same value as that one.

? = 64°
