[tex]\\ \sf\longmapsto 7x+13=90[/tex]
[tex]\\ \sf\longmapsto 7x=90-13=77[/tex]
[tex]\\ \sf\longmapsto x=11[/tex]
Answer:
[tex]62 \degree[/tex]
Step-by-step explanation:
Complementary Angles are added up to 90°
Therefore,
[tex]6x - 4 + x + 17 = 90 \\ 7x + 13 = 90 \\ 7x = 90 - 13 \\ 7x = 77 \\ \frac{7x}{7} = \frac{77}{7} \\ x = 11[/tex]
So,
[tex]ZA = 6x - 4 \\ = 6 \times 11 - 4 \\ = 66 - 4 \\ = 62 \degree[/tex]
