Find the value of x to the nearest tenth

x = 3√5

Step-by-step explanation:

we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:

7² + b² = 10²

b² = 100-49

b² = 51

b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9

we can use the Pythagorean Theorem next to find 'x':

x² + 6² = 9²

x² + 36 = 81

x² = 45

x = √45 = √9·√5 or 3√5

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

no he doesnt because "-16' is negatiive
