Answer:

Triangle GHI is rotating 180° counterclockwise .

Step-by-step explanation:

Given : Triangles.

To find : Which is the image of Triangle ABC for a 180° counterclockwise rotation about P.

Solution : We have triangle ABC .

If we Rotate GHI triangle in counterclockwise 180 degree we get triangle ABC.

We can prove it by rotating triangle ABC in clockwise direction 180° We get triangle GHI.

Therefore, Triangle GHI is rotating 180° counterclockwise .

I NEED HELP CUZ I DONT KNOW HOW TO DO THIS

Area of rectangle = l*w
Area of triangle = (1/2)*l*w

Based on the figure:

Area of triangles = 2*(1/2)*l*w
= 2*(1/2)*24*14 = 336 cm^2

Area of side rectangles = 2*l*w
= 2*44*25 = 2200 cm^2

Area of bottom rectangle = l*w
= 44*14 = 616 cm^2

To find the total surface area, you would add all of the sides together:

336+2200+616= 3152 cm^2

Don’t be afraid to ask any questions, if you have any :D

Your friend claims that it is possible to draw a right triangle where the cosine of either angle (theta) is exactly the same val

avanturin [10]

Answer:

B. No

$Cos \ \theta\neq Cos (90-\theta)\textdegree$

Step-by-step explanation:

-A right angle triangle has two complimentary acute angles and one right angle.

- $\theta$ is usually one of the acute angles and is equivalent to 90º minus it's complimentary acute angle.

-Complimentary angles add up to 90º.

#For complimentary angles:

$Sin \ \theta=Cos \ (90-\theta)\textdegree\\\\Cos \ \theta=Sin(90-\theta)\textdegree\\\\\therefore Cos \ \theta\neq Cos (90-\theta)\textdegree$

The two acute angles cannot have the same Cosine value.

Hence, she's not correct.
