The measures of the angles of a triangle are shown in the figure below. Solve for x.

100°+34°+x°=180°

134°+x°=180°

x°=180°-134°

x°=47°

We know that, In a triangle the sum of all angles is 180°.

Therefore,

Hence, the value of x is 46°.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
