Find the measure of the missing sides of the triangle if each missing angle is 45°
Scorpion4ik [409]

Answer:

the side lengths are both 7

Step-by-step explanation:

Because the angles are both 45 degrees, the triangle is isosceles:  the side lengths are equal.   The hypotenuse of a model 45-45-90 triangle is √2 when the sides are 1 each:

√2        1

------ = -------

7√2       x

                                          1         1

This can be reduced to  ----- = -----

                                           7        x

which makes it obvious that the side lengths are both 7.

Need help with this i don't understand
Oksana_A [137]

Answer:

  1. 7
  2. see below
  3. 5
  4. the rule is not one-to-one

Step-by-step explanation:

Applying the squaring rule to each of the elements of the domain, we get ...

  \begin{array}{cc}\text{Domain}&\text{Range}\\1&1\\-3&9\\-\frac{1}{2}&\frac{1}{4}\\3&9\\2&4\\\frac{1}{4}&\frac{1}{16}\\0.5&\frac{1}{4}\end{array}

__

1. There are 7 different numbers in the Domain list.

2. See above

3. There are 5 different numbers in the Range list.

4. The rule "square me" is not "one-to-one" Two different values in the domain can result in the same value in the range. -3 and 3 both result in 9. -1/2 and 0.5 both result in 1/4.

Please guys I am begging you to help me! This was due yesterday and I need help! SO please help!
jeka57 [31]

Answer:

  • Q3. 12 units
  • Q4. 6.33 units
  • Q5. 66.19°

Step-by-step explanation:

Q3

DE and DF are legs and EF is hypotenuse

  • DE = √EF² - DF²
  • DE = √13² - 5² = √169 - 25 = √ 144 = 12
  • DE = 12 units

Q4

PR is opposite side of angle Q and RQ is adjacent side

  • tan 54 = PR/RQ
  • tan 54 = PR / 4.6
  • PR = 4.6tan 54
  • PR = 6.33 units

Q5

As previous question, using tan as BC is opposite and AC is adjacent leg of angle A

  • tan A = 6.8/3
  • tan A = 2.266
  • A = arctan (2.266)
  • A = 66.19°

PLZ HELP URGENT GET THE BRAINLIEST AND MORE POINTS
lord [1]

Answer:

  • The 27th term is 22

Step-by-step explanation:

Let the first term is a and common difference is d.

<u>The nth term is:</u>

  • aₙ = a + (n - 1)d

<u>We have:</u>

  • a₆ = 15
  • a₉ = 16

<u>The difference of these terms is:</u>

  • (a + 8d) - (a + 5d) = 16 - 15
  • 3d = 1
  • d = 1/3

<u>Then the first term is:</u>

  • a + 5*1/3 = 15
  • a = 15 - 5/3 = 13 1/3

<u>The nth term equation is:</u>

  • aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13

<u>If the nth term is 22, find n:</u>

  • 1/3n + 13 = 22
  • 1/3n = 22 - 13
  • 1/3n = 9
  • n = 9*3
  • n = 27
