The difference of a number and 5 = n - 5

Twice that = 2(n - 5)


‘is’ is the equal sign, so the expression before is equal to 7.


Equation: 2(n - 5) = 7

Find X<br> Please help and explain, whoever answers ill vote brainlest
Dominik [7]

Answer:

x = 35 degrees

Step-by-step explanation:

∠BCA = ∠DAF because they are corresponding angles.

∠BCA + 42 + 103 = 180 (angles in a triangle = 180)

∠BCA = 180 - (42+103)

∠BCA = 35

∠BCA = x (corresponding angles)

x = 35

This is because “trig” solves for the missing angles in a right angled triangle and does not solve for the sides of a right angle triangle.

Hope this helps :)
