Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
Answer:
Step-by-step explanation:
first multiply 4 X 2= 8
8+2x=42
Now you are going to pass 8 to the other side by adding -
2x=42-8
2x=34
Now you are going to divide 34 between 2 to eliminate the 2 multiplying in the other side. 34 between 2= 17
X=17
