Find the measure of all the angles

Mathematics
1 answer:
Sonbull [250]3 years ago
4 0

Step-by-step explanation:

9x+6+5x+90°= 180°

14x+96=180

14x=180-96

14x=84

x= 84/14

x=6

so, <A=5x=5(6)=30°

<B=9x+6=9(6)+6=54+6=60°

<C = 180-(30+60)=180-90=90°

Prove that the median to the hypotenuse of a right triangle is half the hypotenuse,
REY [17]

Answer:

D. 2

Step-by-step explanation:

M(0,2b)

N(2a,0)

Then the midpoint P coordinates are

P\left(\dfrac{2a+0}{2},\dfrac{0+2b}{2}\right)\Rightarrow P(a,b)

Use distance formula to find OP and MN:

OP=\sqrt{(a-0)^2+(b-0)^2}=\sqrt{a^2+b^2}\\ \\MN=\sqrt{(2a-0)^2+(2b-0)^2}=\sqrt{4a^2+4b^2}=2\sqrt{a^2+b^2}

So,

MN=2OP

or

OP=1/2 MN

Use inverse operation to solve the question <br><br> 2/3z = -4<br><br><br> Z= ?
sweet [91]

Answer:

z=(-6)

Step-by-step explanation:

(2/3)*z=(-4)

2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.

2*z=(-12)

z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.

z=(-6)
