The two triangles are similar.

The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45

We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70

Any two triangles that have all 3 angles congruent is similar by AAA.

Answer:

x = $\frac{5}{7}$

Step-by-step explanation:

We can start simplifying this equation by expanding the parenthesis and cross multiplying.

$(7^x)^4 = \frac{7^2 * 7^3}{7^{3x}} = \\\\\\7^{4x} = \frac{7^5}{7^{3x}}\\\\\\7^5 = 7^{7x}\\\\\\$

The exponent 5 and 7x are equal:

$\longmapsto$ Divide both sides by 7

$5 = 7x\\\\x = \frac57$

Each week, mr. jones goes to the grocery store. mr.jones estimates that he will spend $120 when he goes to the grocery store thi

Aliun [14]

Estimated amount that Mr. Jones thought would be spending each week for grocery = $120
Amount actually spent by Mr.Jones in the grocery store = $94
Error in calculation of the amount of spending = (120 - 94) dollars
   = $26
Percentage error in calculation = (26/120) * 100
   = (13/6) * 10
   = 130/6
   = 21.666 percent
   = 21.67 percent
So there is 21.67% error in the calculation of Mr. Jones. I hope you got the answer you were looking for.
