In triangleABC, angle B= 90 degrees, cos(C)=15/17 and AB = 16 what is the measure of Angle A, Angle C and angle AC
Sergeeva-Olga [200]

Answer:

m∠C=28°, m∠A=62°, AC=34.1 units

Step-by-step explanation:

Given In ΔABC, m∠B = 90°, , and AB = 16 units. we have to find m∠A, m∠C, and AC.

As,  cos(C)={15}/{17}

⇒ angle C=cos^{-1}(\frac{15}{17})=28.07^{\circ}\sim28^{\circ}

By angle sum property of triangle,

m∠A+m∠B+m∠C=180°

⇒ m∠A+90°+28°=180°

⇒ m∠A=62°

Now, we have to find the length of AC

sin 28^{\circ}=\frac{AB}{AC}

⇒ AC=\frac{16}{sin 28^{\circ}}=34.1units

The length of AC is 34.1 units

If the discriminant of a quadratic equation is equal to -9, which statement describes the roots?
Mice21 [21]

ANSWER

No real roots.

The roots are complex or imaginary.

EXPLANATION

The quadratic equation

a {x}^{2}  + bx + c = 0

has discriminant,

D =  {b}^{2}  - 4ac

If the discriminant is less than zero , then the quadratic equation has no real roots.

The given discriminant is -9.

Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.
