We present final results of a program for the determination of the Hubbleconstant based on the calibration of the Type Ia supernovae (SNe Ia) using theTip of the Red Giant Branch (TRGB). We report TRGB distances to three SN Iahost galaxies, NGC 3021, NGC 3370, and NGC 1309. We obtain F555W and F814Wphotometry of resolved stars from the archival Hubble Space Telescope data.Luminosity functions of red giant stars in the outer regions of these galaxiesshow the TRGB to be at I ~ QT = 28.2 ~ 28.5 mag. From these TRGB magnitudes andthe revised TRGB calibration based on two distance anchors (NGC 4258 and theLMC) in Jang&Lee 2017, we derive the distances: (m-M)0 = 32.178 +- 0.033 forNGC 3021, 32.253 +- 0.041 for NGC 3370, and 32.471 +- 0.040 for NGC 1309. Weupdate our previous results on the TRGB distances to five SN Ia host galaxiesusing the revised TRGB calibration. By combining the TRGB distance estimates toSN Ia host galaxies in this study with the SN Ia calibration provided by Riesset al. 2011, we obtain a value of the Hubble constant: H0 = 71.66 +- 1.80(random) +- 1.88 (systematic) km/s/Mpc (a 3.6% uncertainty includingsystematics) from all eight SNe, and H0 = 73.72 +- 2.03 +- 1.94 km/s/Mpc (a3.8% uncertainty) from six low-reddened SNe. We present our best estimate, H0 =71.17 +- 1.66 +- 1.87 km/s/Mpc (a 3.5% uncertainty) from six low-reddened SNewith the recent SN Ia calibration in Riess et al. 2016. This value is betweenthose from the Cepheid calibrated SNe Ia and those from the Cosmic MicrowaveBackground (CMB) analysis, lowering the Hubble tension.
