Answer:
x=49
Step-by-step explanation:
los 3 angulos del triangulo deben de sumar 180
76+55=131
180-131=49
76+55+49=180
Answer:
x=26 is the answer
Step-by-step explanation:
See picture for explanation.
Answer:
92.75 cm^2
Step-by-step explanation:
Area of triangle ADC
= (1/2)×4.5×12 = 27
Area of triangle ACB
=(1/2)×12×5 = 30
Find AB using pythagoras theorem on triangle ABC:
AB^2 = 5^2 + 12^2 = 25 + 144
AB^2 = 169
AB = 13cm
Area of triangle AGB
= (1/2)×13×5.5 = 35.75
Total area = sum of the areas of the 3 triangles found above
= 27 + 30 + 35.75 = 92.75 cm^2
