How many right angles can be in an obtuse triangle?

1 answer:

STatiana [176]3 years ago

By definition, an obtuse triangle has an obtuse angle (angle greater than 90 degrees). The 3 angles of a triangle always add up to 180 degrees. Since one of our angles is greater than 90 degrees, the other 2 have to add up to less than 90 degrees, so there can be NO RIGHT ANGLES.

zysi [14]

Answer:

7.3%

Step-by-step explanation:

Given:

<em>Formula for Rate of interest </em> $R$ :

$R=\dfrac{i}{Pt}$

Where $i$ is the rate of interest.

$P$ dollars is the loan and

$t$ years is the time for which interest is to be paid

$P =\$690\\t=3\ years\\i=\$151.11$

To find:

$R=?$

Solution:

Putting the given values in the formula:

$R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073$

Multiply the above value with 100 to find the percentage.

i.e.

$R=0.073\times 100 = \bold{7.3\%}$

Therefore, the answer is <em>7.3%</em>
