Answer:
38.7°
Step-by-step explanation:
We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where
SOA stands for
Sin Ф = opposite side/hypotenuses side
CAH stands for
Cosine Ф = adjacent side/hypotenuses side
TOA stands for
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering the triangle with respect to angle x, 8cm is the opposite side, 10cm is the adjacent side
hence
Tan x = 8/10
Tan x = 0.8
x = tan -1 0.8
= 38.7°
Option A
-x + 6y = 42 is the standard form
<u>Solution:</u>
Given that we have to write 
in standard form
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
Given equation is:
Let us convert the above equation into standard form
Make the denominator same in R.H.S
Solve the above equation
Move 6 from R.H.S to L.H.S
Bring all the terms to one side, leaving only constant on R.H.S
The above equation is of form Ax + By = C
Thus option A is correct
Answer:
35
Step-by-step explanation:
base × height so just multiple 7 and 5
9/16 is the original fraction. 9+3 = 12 and 16-1 =15. 12/15 = 4/5
The answer is 926 :)))
i hope this is helpful
have a nice day
