Answer:
Image result for A triangle has two angles that are 33 degrees and 54 degrees. What is the third angle?
If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°.
Step-by-step explanation:
<span>If a triangle does not have one angle greater than 90°, then it is not an obtuse triangle.
Remember that you create a contrapositive by inverting and swapping both terms. So if you have
if A then B
the contrapositive would be
if not-B then not-A
Since you've been given
"If a triangle is an obtuse triangle, then it has one angle with measure greater than 90°"
the contrapositive would be something like
"If a triangle has no angles with a measure greater than 90°, then it is not an obtuse triangle."
So, now look at the available choices and see what matches in intent even if it's not phrased exactly the same.
The option
"If a triangle does not have one angle greater than 90°, then it is not an obtuse triangle."
matches the intent of the contrapositive that we constructed independently and is the correct answer.</span>
Using Pythagorean theory the square of the hypotenuse minus the square of the base equals the square of the other side (altitude).
So 8*8=64, 4*4=16, 64–16=48 so the altitude of the triangle is the √48.
Answer:
Step-by-step explanation:
1. A = 68
B = 112
c = 68
2. A = 127
3. A = 70
B = 55
C = 25
