Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so
also
y is equal to twice the sum of the smaller number and 1.
so
so the system of equations become
solving
Therefore, there is NO solution.
Answer:
x= √10/2
Step-by-step explanation:
if you use trig. functions:
sin 45° = opposite side /hypothenuse = x/√5
sin 45° = √2/ 2
√2/2 = x/√5 multiply both sides by √5
x= (√2*√5)/2 = √10/2
if you use that is a 45-45-90 special triangle
the sides are x, and hypothenuse must be x√2 in this type of triangles so in our case:
x√2 = √5 divide both sides by √2
x= √5/√2 multiply by √2/√2 which =1 and help us get rid of the radical from the denominator
x= (√5*√2)/ (√2*√2) = √10/2

Answer:
<em>36:60:84</em>
<em>A : B : C</em>
<em>36° : 60° : 84°</em>
<em>A= 36°</em>
<em>B= 60°</em>
<em>C=84°</em>
Step-by-step explanation:
<em>3:5:7 =15</em>
<em>180÷15=12</em>
<em>3×12=36</em>
<em>36:x:y =180</em>
<em>5×12=60</em>
<em>36:60:y =180</em>
<em>7×12=84</em>
<em>36:60:84 =180</em>
