Answer:
<h2>46 cm</h2>
Step-by-step explanation:
first ,we use the Pythagorean theorem to determine the width:
width = √(17^2-15^2) = 8
then
perimeter = 2(width+lengt) = 2(8 + 15) = 2×23 = 46
Answer:
6) x = 17 ft
7) 42 in
Step-by-step explanation:
6) length of the tangents are equal.
2x - 7 = 27
2x = 34
x = 17
7) if you draw a line from T passing through the centre of the circle, it will divide the triangle into two congruent triangles
Perimeter = 2(5+7+9) = 42 in
Answer:
Yes they are
Step-by-step explanation:
Conguent shapes are still conguent even if rotated and flipped. As long as their angles and length of sides are the same, they are congruent
Answer: y=-1/2x-3
Step-by-step explanation:
y=mx+b
y=-1/2x+b
Now let’s plug in (4,-5) into that equation
-5=-1/2(4)+b
-5=-2+b
b=-3
Now to put it all together, we get y=-1/2x-3
B. The y-intercept is 38. Since the graph opens down, the a-value (-16t^2) is negative. The c-value (38) cannot be negative since on the graph, the line goes through 38, not -38.
