Find Angle B 100° 150 200 100

Mila [183]

Answer:

50°

Step-by-step explanation:

An inscribed angle is half the measure of its intercepted arc. Here, arc AC is ∠B's intercepting arc. Arc AC is 100°, and 100/2 = 50, so ∠B is 50°.

7x + 2y = 17 2x - 2y = 1 =

DerKrebs [107]

Answer:

$(2,\frac{3}{2}})$

Step-by-step explanation:

For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

$\left \{ +{{7x+2y=17} \atop {2x-2y=1}} \right. \\\\9x=18\\x=2$

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

$7x+2y=17\\7(2)+2y=17\\14+2y=17\\2y=3\\y=\frac{3}{2}$

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is $(2,\frac{3}{2}})$ .

WILL GIVE BRAINLIEST! What is the answer for question (iv)? please help!

Leviafan [203]

Step-by-step explanation:

$\triangle ABC \sim \triangle ADE... (given) \\\\\therefore \frac {AC}{AE} = \frac {BC}{DE}.. (csst) \\\\\therefore \frac {5}{5+2x} = \frac {x+3}{4x+1}\\ \\ \therefore \: 5(4x + 1) = (5 + 2x)(x + 3) \\ \therefore \:20x + 5 = 5x + 15 + 2 {x}^{2} + 6x \\ \therefore \:20x + 5 =2 {x}^{2} + 11x + 15 \\ \therefore \:2 {x}^{2} + 11x + 15 -2 0x - 5 = 0\\ \therefore \:2 {x}^{2} - 9x + 10 = 0\\ \therefore \:2 {x}^{2} - 5x - 4x+ 10 = 0\\ \therefore \:x(2x - 5) - 2(2x - 5) = 0 \\ \therefore \:(2x - 5)(x - 2) = 0 \\ 2x - 5 = 0 \: \: or \: \: x - 2 = 0 \\ x = \frac{5}{2} \: \: or \: \: x = 2 \\ x = 2.5 \: \: or \: x = 2 \\ x = 2.5 \: is \: largest \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{AC ^{2} } {AE^{2} } \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{5 ^{2} } {(5 + 2x)^{2} } \\ = \frac{25}{(5 + 2 \times 2.5)^{2} } \\ = \frac{25}{ {10}^{2} } \\ = \frac{25}{100} \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{1}{4} \\$
