Answer:
Acute
Step-by-step explanation:
Each angle is less than 90 and any angle less than 90 is acute, therefore, we can say without a doubt, that this triangle is acute
It would be nice If I could read it better. The answer is C if is says angle 3 and angle 5.
Answer:r=8
Step-by-step explanation:
A should be the correct answer. As you can see, the cubes on the lowest level is 1 cube. The second level is equal to 2 cubes and the highest level is equal to 3 cubes
That triangle is isosceles, so the bottom two angles will always be equal. With that said, the equation will be 2(65), and that equals 130. After that, subtract 180-130, and that gives you x! In total, your calculations should look like this:
2(65)
180-130
x=50°
