Answer:

f I think

Step-by-step explanation:

A/B has 48 C would be 90 but I doesn't have that

The true equations are given below and this can be determined by using the sum of interior angle properties and the trigonometric functions.

Given :

  • A triangle ABC is given.
  • Angle A = 48 degrees.

The following steps can be used in order to determine the true equations:

Step 1 - First, determine the measure of angle B by using the sum of interior angle property.

[tex]\rm \angle A + \angle B + \angle C = 180^\circ[/tex]

48 + 90 + [tex]\rm \angle B[/tex] = 180

[tex]\rm \angle B[/tex] = 42 degrees

Step 2 - Now, the trigonometric functions can be used in order to determine the true equations.

Step 3 - The expression of the sine function is given below:

[tex]\rm sin42 = \dfrac{b}{c}[/tex]

Step 4 - The expression of the cosine function is given below:

[tex]\rm cos48 = \dfrac{b}{c}[/tex]

Step 5 - The expression of the tangent function is given below:

[tex]\rm tan42 = \dfrac{b}{a}[/tex]

[tex]\rm tan48 = \dfrac{a}{b}[/tex]

Therefore, the true equations are given by options B), C), E), and F).
