Answer:
<h2>y - 5 = -1(x + 3)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
We have m = -1 and the point (-3, 5). Substitute:
We can use the Pythagorean theorem to solve for the perimeter of the kite.
a² + b² = c²
3² + 4² = UV²
9 + 16 = UV²
25 = UV²
√25 = √UV²
5 = UV
In the kite, adjacent sides are the same so UV = VW
3² + 9² = UX²
9 + 81 = UX²
90 = UX²
√90 = √UX²
9.49 ≈ UX or 3√10 ≈ UX
Now, add to find the perimeter.
5 + 5 + 9.49 + 9.49 or 5 + 5 + 3√10 + 3√10
28.98 or 10 + 6√10
Therefore, the perimeter is approximately 28.98 or 10 + 6√10
Best of Luck!
Answer:
102 degrees.
Step-by-step explanation:
Because the 3.3's are congruent (the same), this triangle is isosceles.
A property of isosceles means that the two angles are congruent.
39+39= 78
This means that the last angle must be 180-78.
I assume you're asking about #19?
24 students total, teacher gives each PAIR of students 3 magnets.
There are 12 pairs of students, then, and the teacher has given 9 of those pairs their 3 magnets, leaving 3 pairs without their magnets.
3 pairs remaining to get 3 magnets (3*3=9)
The teacher needs 9 more magnets.
