Mang Ambo was admitted to the hospital because his body temperature is 39.6ºC. How much higher is his temperature than the normal? A. What is asked? B. What is the operation to be used? C. Write the mathematical sentence? D. What is the answer?

2.6 degree Celsius

Step-by-step explanation:

A) It is asked that by how much degrees the temperature of Mang Ambo is higher than that of normal body temperature (37 degree Celsius) of human being

B) Subtraction operation will be used

C) Temperature higher than normal human body temperature

D) degree Celsius

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
