Answer:
sin 52°= AB/x
sin 52°=AB/7.7
<em><u>AB= 6.06 m</u></em>
Answer:
89
Step-by-step explanation:
add 5 so 84 and then you add 5 to that and the answer you get is 89
Answer:
Step-by-step explanation:
I'll answer the question, but before I do, let me crab about the reliance on a diagram. You should never have to answer a question where you make assumptions about the diagram. It should state the the longest leg in one triangle = 2x - 4, and the hypotenuse in the larger triangle is 42, while in the smaller one it is x + 8\
Added to which you have to state that there is a ratio between the large triangle and the small one.
24/(2x - 4) = (x + 8)/42 Cross Multiply
24*42 = (x + 8)*(2x - 4) Remove the brackets. Combine the left
1008 = 2x^2 - 4x + 16x - 32 Combine the right and switch
2x^2 + 12x - 32 = 1008 Subtract 1008
2x^2 + 12x - 1040 = 0 Divide by 2
x^2 + 6x - 520 = 0
(x + 26)(x - 20) = 0
x = - 26 which has no meaning
x = 20 which is the answer.
2x - 4 = 2*20 - 4 = 36
x + 8 = 28
I'm not sure what you want -- the side lengths or just x.

I hope that is useful for you :)
Answer:
1). (x, y) → [(x + 7), (y + 1)]
2). (9, 10)
3). (x, y) → (-x, y)
4). (-2, 9)
5). (-9, 10)
Step-by-step explanation:
Given: Triangle ABC is translated 7 units right and 1 unit up, then reflected across the y-axis.
Rule for the translation of A is,
(x, y) → [(x + 7), (y + 1)]
After the translation point A moves to,
(2, 9) → [(2+7), (9+1)]
→ (9, 10)
The rule for a reflection over the y-axis is,
(x, y) → (-x, y)
The coordinates of A after the reflection are,
(2, 9) → (-2, 9)
The final position of A,
(-9, 10)
