The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
Answer:
1. is a 30 60 90 triangle so x = 30
pardon my bad handwriting for below
2.
STEP 1: subtract the angle you have from 180
STEP 2: add your x values together, if there is a non x number (such as + 10) balance it out on the other side by adding or subtracting
STEP 3: divide so that x has no coeffecient in front of it
STEP 4: substitute x values with the value you got
STEP 5: verify by adding the angles you got, it'll be correct if it equals 180
In the diagram, we know that ∠Y and ∠X appear to be similar. We also note the bottom triangle is equal to 180°. So, Y° + 50° + 60° = 180.....Y = 70°
Since Y = 70°, X also is equal to 70°
WY = a = 4
ZY = b = 3
As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c
a2+b2=c2 (4)2+(3)2=C2 16+9=C2 C2=25
Taking square root on both sides
√c2= √25 c=5
The value of c is 5 units.
