Answer:

41°

Step-by-step explanation:

SOHCAHTOA

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

tanx = opp / adj

opposite from angle x is 12 centimeter side

adjacent to angle x is 14 centimeter side

the other side is the hypotenuse because it is opposite the right angle

tanx = 12 / 14

use the inverse tangent button (usually press 2nd or shift on calculator and then press tangent button):

Type in calculator: $tan^{-1}(\frac{12}{14})$

Solve using the order of operations: 6.3 7 squared x 3.1

SVETLANKA909090 [29]

6.37² x 3.1

First is Exponents (6.37²):

40.6 x 3.1

Then, Multiplication:

40.6 x 3.1 = 125.9.

To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.

Example:

(5-2)5 + 2² / 6 -1 = ?

First, Parentheses:

(3)5 + 2² / 6 - 1

Then, Exponents:

(3)5 + 4 / 6 - 1

Then, Multiplication:

15 + 4 / 6 - 1

Then, Division:

15 + 0.7 - 1

Then, Addition:

15.7 - 1

Then, Subtraction:

14.7

So that means, (5-2)5 + 2² / 6 -1 = 14.7

liz and alana each participated in the high jump at the track meet. liz's high jump was 1 meter. alana's high jump was 132 centi

USPshnik [31]

1 meter is the same as 100 centimeters, so since Liz jumped 100 centimeters, and Alana jumped 132, Alana jumped higher.
