Answer:
ionic
it is a mixture of a nonmetal and a metal which is what makes ionic compounds
covalent is a nonmetal and nonmetal

Answer:
55.52°
Explanation:
Concept tested: Sine rule of triangles
We need to know the sine rule
- According to sine rule, if the three sides of a triangle are a, b and c and the corresponding angles, A, B and C
- Then,

In this case;
- If we take, a = 5.7 units and A = 70°, and
b= 5 units, B = x°
- Using the sine rule we can find the value of x
Therefore;

Then;



Therefore, X = 55.52°
Therefore, the value of x in the triangle is 55.52°
