Answer:
yes, ASA
Step-by-step explanation:
You have two angles and the included side of two triangles, so you can prove the triangles are congruent by ASA.
Step-by-step explanation:
tan(A/2)
tan(A/2)=sinA/1+cos A
tan(A/2)= 5/13÷1+12/13
tanA/2=1/5
Answer:
To calculate percentages, start by writing the number you want to turn into a percentage over the total value so you end up with a fraction. Then, turn the fraction into a decimal by dividing the top number by the bottom number. Finally, multiply the decimal by 100 to find the percentage.
Step-by-step explanation
Answer:
Step-by-step explanation:
Before we start calculating we have to first note that the angles in a triangle always add up to 180°. Therefore in order to find the missing angle U we have to add both the angles we know, 37° and 63°, then subtract the sum from 180°
