Isn't it 89 not 19 and if its that, its 12 and 77
No.4- This is not a triangle since one side should be less than the sum of the 2 other sides. In this case 8=3+5, hence it's equal & not smaller
N0.5- This is an isosceles triangle & there are an infinity of triangles with the mentioned degrees. (these are called similar triangle)
No6- This is a unique triangle
No.7- If the plane is parallel to the bases, then the slicing is a cercle.
But if the plane (Parallelogram) is tilt, then the slicing is an ellipse
If 3z=2z+5 and z=5, then you’d just plug the 5 in.
3(5)=2(5)+5 —> 15=10+5 —> 15=15
This statement is TRUE because 15 does equal 15.
I hope this helps. :)
Answer:
The movie theater is 3 miles away from the the ice cream parlor.
Step-by-step explanation:
The position of Becky's school (S) and the movie theater (M)and the ice cream parlor (I) make a right triangle.
Hence, Δ SMI is a right triangle with ∠ M is the right angle i.e. 90°.
Now, given length of segment SM is 4 miles and the hypotenuse i.e. line segment SI = 5 miles.
Hence, applying Pythagoras Theorem,
SI² = SM² + MI²
⇒ 5² = 4² + MI²
⇒ MI = 3 miles.
Therefore, the movie theater is 3 miles away from the ice cream parlor. (Answer)
Answer:
Step-by-step explanation:
(4 - 7)/(5 + 10) = -3/15 = -1/5
y - 4 = -1/5(x - 5)
y - 4 = -1/5x + 1
y = -1/5x + 5
