Answer:

y = 20

Step-by-step explanation:

Since AB and AC are congruent then the triangle is isosceles, thus

∠B = ∠C = 25°

To find ∠A subtract the sum of the 2 angles from 180°

∠A = 180° - (25 + 25)° = 180° - 50° = 130°, thus

3y + 70 = 130 ( subtract 70 from both sides )

3y = 60 ( divide both sides by 3 )

y = 20

How do I solve for AB? (rounded to the nearest tenth)
kolbaska11 [484]

Answer:

The answer would be 8.1

Step-by-step explanation:

For the smaller triangle, you use the pythagorean theorem. a squared + b squared = c squared.

To find one of the legs, you do 5 squared - 3 squared = b squared.

25 - 9 = b squared. (BD)

16 = b squared

4 = b

Now for the bigger right triangle. You still use the same tactic.

7 squared + 4 squared = c squared (which is AB)

49 + 16 = c squared

65 = c squared

That means c would equal: square root of 65, which is 8.0622577483 which rounds to 8.1

I don’t get this can someone explain this
LekaFEV [45]

Answer:

15.7 units

Step-by-step explanation:

AB = 6, BC = 3

Therefore by Pythagoras theorem

AC = \sqrt{45}

perimeter \: of \:  \triangle \: ABC \\  = 6 + 3 +  \sqrt{45}  \\  = 9 + 6.70820393 \\  = 9 + 6.7 \\  = 15.7\: units
