I know its one of the congruent ones, as one is for sure a 90 degree angle, on top of an 180 degree angle, which by law of supplementary angles makes the other one 90 degrees. Not sure on the postulate, maybe someone else can help with that.

Find the measure of the indicated angle to the nearest degree.
deff fn [24]

Given:

A right triangle with legs 5 units and 6 units.

To find:

The measure of angle opposite of side whose length is 5 units.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Opposite}{Adjacent}

Let \theta be the missing angle. Then, for the given triangle,

\tan \theta=\dfrac{5}{6}

\theta=\tan^{-1}\dfrac{5}{6}

\theta=39.805571^\circ

Round the value to the nearest degree.

\theta\approx 40^\circ

Therefore, the measure of the required angle is 40 degrees.

Evaluate using properties of arithmetic operations. 12∙121∙13÷(26∙11)∙7÷11
Anika [276]

Answer:

0.1978

Step-by-step explanation:

According to the rule of BODMAS (or FEDMAS), let us do the bracket first.

26·11 = 286

Now, do the multiplication from the left.

12·121·3 = 4356

286·7 = 2002

Now, do the division from the left.

\frac{\frac{4356}{2002} }{11}

=\frac{4356}{2002(11)}

=\frac{396}{2002}

= 0.1978
