Answer:

d=7

Step-by-step explanation:

To find d youll have to find it. 9d + 4 = 2d + 53 minus 2d on both sides> 7d+4=53 now minus 4 on both sides> 7d=49 divide 49/7 > d=7

First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48

Answer:

$\huge{ \bold{ \boxed{ \sf{x = \frac{1}{3} }}}}$

☪ First , Let's know about Exponential Equation :

⤿ Let's take an equation : $\sf{ {2}^{x} = 8}$ .

In this equation , the variable ' x ' is the exponent of the base 2. Such an equation in which variable appears as an exponent of a base is known as exponential equation. The following axioms are useful while solving the exponential equations :
