The complement of an angle is three times the measurements of the angles find the measurements of the larger angle

Mathematics

CaHeK987 [17]3 years ago
3 0

Answer:  

If we know that 2 angles are complements of each other, then they add up to 90 degrees. Knowing this, if we know that the complement of an angle X has an angle value that is 3 times greater, we can write that as such: X + 3X = 90 => 4X = 90. We solve for X to get: 22.5 degrees.

What is the sum of the first seven terms of the geometric series 2 - 10 +50 -...?
Umnica [9.8K]

Answer:

26042.

Step-by-step explanation:

What's the first term of this geometric series?

2.

What's the common ratio of this geometric series?

Divide one of the terms with the previous term. For example, divide the second term -10 with the first term 2.

\displaystyle r = \frac{-10}{2} = -5.

What's the sum of this series to the seventh term?

The sum of the first n terms of a geometric series is:

\displaystyle a_1 \cdot \frac{1-r^{n}}{1-r},

where

  • a_1 is the first term of the series,
  • r is the common ratio of the series, and
  • n is the number of terms in this series.

\displaystyle 2 \times\frac{1- (-5)^{7}}{1- (-5)}=26,042.
