find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

Find the value of the variable that results in congruent triangles for numbers 6 and 8.
mariarad [96]

Answer:

x = 28

Step-by-step explanation:

From the figure attached,

AC ≅ FH [Given]

BC ≅ GH [Given]

AB ≅ FG [Given]

ΔABC ≅ ΔFGH [By SSS property of congruence]

Since, m∠A + m∠B + m∠C = 180°

50° + 69° + m∠C = 180°

119° + m∠C = 180°

m∠C = 180° - 119°

m∠C = 61°

m∠C = m∠H [Since, ΔABC ≅ ΔFGH]

(2x + 5)° = 61°

2x = 61 - 5

2x = 56

x = 28
