Answer:
10
Step-by-step explanation:
4+5=9 and 1/2+1/2 =1 so 9+1=10
Answer:
x=25 degrees
Step-by-step explanation:
**triangle equals 180
1. add 36 and 61 (you get 97)
2. Subtract 180-97=83
3. Now Set up the equation
4x-17=83
4. Add 17 to both sides and on the left it will cancel and become 4x=100
5. Then divide both sides by 4 resulting in 25 degrees
Answer:
he was supposed to add three on both sides
Answer:
90degrees
Step-by-step explanation:
To get the measure of angle C, we will use the cosine rule as shown;
AB² = AC²+ BC² - 2(AC)(BC)cos C
85² = 13²+ 84² - 2(13)(84)cos C
7225 = 169 + 7056 - 2184cosC
7225 - 7225 = -2184cosC
0 = -2184cosC
cosC = -0/2184
cosC = 0
C = arccos0
C = 90degrees
Hence the measure of angle C is 90degrees
