Answer:

y+2x=7 (1)

x=3+y (2)

Replace x = 3+y (2) into (1) => y+2(3+y) = 7

=> y = 1/3 and x = 3+1/3 =10/3

By using parallel lines and transversal lines concept we can prove m∠1=m∠5.

Given that, a║b and both the lines are intersected by transversal t.

We need to prove that m∠1=m∠5.

<h3>What is a transversal?</h3>

In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points.

m∠1+m∠3= 180° (Linear Pair Theorem)

m∠5+m∠6=180° (Linear Pair Theorem)

m∠1+m∠3=m∠5+m∠6

m∠3=m∠6

m∠1=m∠5 (Subtraction Property of Equality)

Hence, proved. By using parallel lines and transversal lines concept we can prove m∠1=m∠5.

Please help on this math question!!
katrin2010 [14]

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= \sqrt{(7\sqrt{(33)^{2} }- (33)^{2}

=\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}

The side that continues next to 33: x -33

Applying similarity property on right triangles:

\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}

(33)(x-33)=(4\sqrt{33} )^{2}

33x-1089=528

33x=528+1089

x=\frac{528+1089}{33} =49

Hope this helps
