Mathematics

Answer:

a). m∠a = 62°

b). m∠b = 118°

Step-by-step explanation:

a). Since, an angle inscribed in a semicircle is a right angle,

   m∠ACB = 90°

   By triangle sum theorem in ΔABC,

   m∠CAB + m∠ACB + m∠ABC = 180°

   28° + 90° + m∠ABC = 180°

   118° + m∠ABC = 180°

   m∠ABC = 180°- 118°

   a = 62°

b). Since, quadrilateral ABCD is a cyclic quadrilateral,

    m∠ADC + m∠ABC = 180°

    b + a = 180°

    b + 62° = 180°

    b = 180° - 62°

    b = 118°

Suppose DK is an angle bisector of △DEF. Given: EK=2, FK=5, DF=10. Find DE.
Inessa [10]

Answer:

  DE = 4

Step-by-step explanation:

The bisector divides the triangle into proportional segments, so ...

  FK/DF = EK/DE

  5/10 = 2/DE . . . . substitute given values

  DE = 4 . . . . . multiply by 2DE

1. inverse of a conditional Formed by exchanging the hypothesis and the conclusion and negating both of them. 2. contrapositive
Gekata [30.6K]

See below for the vocabularies and their correct definition

<h3>Missing part of the question</h3>

Match the following vocabulary

<h3>How to match the vocabulary?</h3>

The terms are given as:

  • inverse of a conditional
  • contrapositive of a conditional
  • converse of a conditional

To get the inverse of a conditional, the hypothesis and the conclusion are negated, without interchanging them.

So, we have:

Inverse of a conditional ⇒ A new statement formed by negating both the hypothesis and the conclusion.

To get the contrapositive of a conditional, the hypothesis and the conclusion are negated, after interchanging them.

So, we have:

Contrapositive of a conditional ⇒ Formed by exchanging the hypothesis and the conclusion and negating both of them.

To get the converse of a conditional, we simply interchange the hypothesis and the conclusion, without negating them

So, we have:

Converse of a conditional ⇒ A statement formed by interchanging the hypothesis and the conclusion in a conditional statement.
