A triangle has side lengths of 18 cm, 80 cm, and 81 cm. Classify it as acute, obtuse, or right
1) Wayne used this diagram to compute the distance from Ferris, to Dunlap...
25 mi.
2) A triangle has side lengths of 18cm, 80 cm, and 81 cm. Classify it as acute, obtuse, or right.
Acute
3) The area of a square garden is 200 m^2. How long is the diagonal?
20 m
4) A conveyor belt... (I'm not going to type this all down)
14 ft
5) Find the missing value to the nearest hundredth.
tan ___ = 73
89.22
6) Write the ratio for sin A and cos A. The triangle is not drawn to scale.
sin A = 48/50, cos A = 14/50
7) (Sorry you're on your own.)
last part is on brainly. just search up "find the lengths of the missing sides in the triangle 7 45" and it should be one of the first links
With two long, almost equal, sides and a short side, you can visualize it in your head. It is acute.
It certainly is not a right angle, since 18^2 + 80^2 does not equal 81^2.
The law of cosines can be used to answer the problem numerically.
The largest angle C is opposite the longest side, c.
c^2 = a^2 + b^2 -2ab cosC
When c^2 < (a^2 + b^2), as it is here, cosC must be positive, making C an acute angle.
1. 25 mi
2. Acute
3. 20m
4. 14ft
5. 89.22
6. sin A= 48/50, cos A = 14/50
Its an acute angle
@senchou is right for honors
Bruh senchou only got 1 wrong so like quit making it sound like they didn't get any Right quit wasting y'alls time just to say there wrong.
@senchou is 100% WRONG, the 100% CORRECT PERSON is @dabi
senchu is correct for honors geometry
dabi is right I got an 100%
senchou is very wrong
Hello
No its not a right triangle.
Help
Sure! What do you need help with?
Heres the answer to 7 from brainly:
The values of and are required.
The required values are
The given triangle is a right angled triangle.
Two given angles are and
The sum of the angles is
The missing angle is
Since, the two angles are equal the side opposite the angles will also be equal.
So,
Applying the Pythagoras theorem.
A triangle has side lengths of 9 inches, 18 inches, and 17 inches. What kind of triangle is it?
yep dabi is mostly right except they changed number 5 to 300 m^2.
new answers :
1. Wayne used this diagram to compute......
B-25mi
2: A triangle has side lengths of 18cm, 80cm, and 81cm
C-acute
3:The area of a square garden is 300 m^2. How long is the diagonal?
C- 10_/6m
4: A conveyor belt.... too lazy
C- 14ft
5: Find the missing value to the nearest hundredth. ten_=73
D-89.22
6:Write the rations for sin A and cos A. (Triangle with sides 14, 50, 48)
B- sin A= 48/50, cos A=14/50
