2. measurements can be any to complementary angles.
for example, 60 & 30
3. the 2 sides are equal. Since it is an isosceles triangle.
4.an equi.triangle can never be right angled. Since, all angles are 60° in an equi.triangle.
5. right triangle can never have an obtuse angle since one angle is already 90°. therefore the other two agles are supposed to be acute angles.[ since sum of all angles in a triangle is 180°]
The answer is 75 degrees. These are supplementary angles so
180-105 = 75
Answer:
Step-by-step explanation:
Well, first let's look at our trig identities. We can set up a cosine function using the given angle:
(adjacent/hypotenuse)
Then, multiplying both sides by 16 gives us:
Hope this helps!
Square root of 324 = 18 inches.
Perimeter = 18 inches x 4 = 72 inches.
18 times 4 because each side of square tile equals to 18 inches and there's 4 sides.
The answer is 72 inches.
Hope this helps.
Answer:
1. KJL=55 JLK=55 JKL=70
2. x=12 (you can just plug X in and get the angle measures they will all equal 180 alltogether)
3. x=2
4. x=7
5. 23 degrees
6. i dont remember how to do i sorry
7. 20
8. 45 degrees
9. i dont know
10. 120 degrees
11. cant see the picture
